This is the best, most complete demonstration I've found for this algorithm. The first example was perfect. I especially like how the professor modified it as a side note to show what should be done when a pattern contains repeated characters.
Sorry to be so offtopic but does someone know a tool to log back into an Instagram account?? I was dumb lost the password. I love any help you can give me
@Lyle Brendan Thanks so much for your reply. I found the site on google and Im trying it out now. Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
I was looking for this topic everywhere but after watching multiple videos I can surely say that this is the Best Explanation of this topic for Bad Character so far . Can you also make a video for Good Suffix Heuristic.
5:09 if u add a imaginary char 's' to the pattern then the length will be 7 for the pattern and hence (in the imaginary situation) the value for the second 'a' is 1 not 0
Great explanation. However, one thing I want to point out about the shift at 13:17 When we found a mismatch at index 5 between M (in T) and G (in P), we don't want to shift the entire pattern. Imagine we're comparing the following i: 0 1 2 3 4 5 6 7 T: W E L C O M E O L L E G E P: E O L L E G E If we followed the logic in the video, when we find the mismatch between M (in T) and G in (P), our loops exit and return a 'P is not in T' answer because we head straight to index 7 when we should be on index 6 . What we should do is, move our index to mismatchIndex + 1. In my example, mismatchIndex is 5 so our comparison starts from index 6 which will be between the first element of P and the 6th element of T.
It is because of the calculation of the bad match table, specifically the value for the last character in the pattern. In the video she says the value for the last character should always be the length of the pattern, so in the case for E0LLEGE, E in the bad match table is 7. But the value of the last character should only be equal to the length of the pattern if it had not been defined before. And From the pattern E has already been defined at index 0 and index 4, Hence the final value for E in the bad match table should be E=7-4-1=2 The bad match table would look like. E O L G * 2 5 3 1 7 That is from my understanding, correct me if am wrong.
Ma'am your should make more vidoes, your explanation is so good, The one and only video on youtube which explain Boyer Moore pattern Matching algorithm so nice and easy way, Tnq so much ma'am.........................................................................................
28k+ views and just one video on the channel, ma'am please make more videos you explain so nicely (itna pyara smjhaya hai aapne 🥺❤) Make more videos and soon you will reach heights!❤ Make videos on more algorithms like this!❤
Very nice explanation and please increase your voice a little bit in middle of the video and please upload more videos on all topics ,you are the best teacher
@bharathi Ramesh your explanation for Boyer Moore Pattern Matching algorithm is not working for this example, txt = ababdabacdababcabab pat = ababcabab
I believe it is because of the calculation of the bad match table, specifically the value of the last character, in the bad match table, the value of the last character should be equal to the length of the pattern if it had not already been defined, as seen in your pattern b has already been defined so instead of b=9, b=2. After calculating the bad match table it should be a b c * 1 2 4 9
The shaky camera and flickering light annoyed me and got dizzy. Make a video with a camera stand and good light. Your teaching method is amazing and easy to understand. Thank you.
This is the best, most complete demonstration I've found for this algorithm.

The best explanation on TY for BMA
I was looking for this topic everywhere but after watching multiple videos I can surely say that this is the Best Explanation of this topic for Bad Character so far . Can you also make a video for Good Suffix Heuristic.
super duper explanation from mam mastered it in 15 min .....support this channel guys
Continue doing such videos…such an amazing explanation!!! Hats off ma’am. You made an ocean look like a drop of water 👏🏻👏🏻👏🏻
Went through like 7 to 8 videos and finally found better.
Well explained mam...now I totally understand the boyer Moore algorithm..please mam make video on brute force pattern matching algorithm...🙏🙏🙏
Your teaching skill is amazing
Thank you so much for this lecture
Amazing clear, concise and easy to understand explanation, thank you very much!
mam ur explaination is just perfect!!
Perfect explanation.....Hope you will do much more vidoes like this.
very well explained need more videos, hope you can benefit many students using your knowledge
I went from not getting this algorithm at all to fully getting it before this video was over... you have an incredible talent!!!
Tq mam I understood the concept very well
5:09 if u add a imaginary char 's' to the pattern then the length will be 7 for the pattern and hence (in the imaginary situation) the value for the second 'a' is 1 not 0
thank you maam today my exam this topic got cleared before 3 hrs
Good 👍 luck mam very good teaching and you are look gorgeous😍
Great explanation. However, one thing I want to point out about the shift at 13:17
When we found a mismatch at index 5 between M (in T) and G (in P), we don't want to shift the entire pattern. Imagine we're comparing the following
i: 0 1 2 3 4 5 6 7
T: W E L C O M E O L L E G E
P: E O L L E G E
If we followed the logic in the video, when we find the mismatch between M (in T) and G in (P), our loops exit and return a 'P is not in T' answer because we head straight to index 7 when we should be on index 6 . What we should do is, move our index to mismatchIndex + 1. In my example, mismatchIndex is 5 so our comparison starts from index 6 which will be between the first element of P and the 6th element of T.
It is because of the calculation of the bad match table, specifically the value for the last character in the pattern.
In the video she says the value for the last character should always be the length of the pattern, so in the case for E0LLEGE, E in the bad match table is 7.
But the value of the last character should only be equal to the length of the pattern if it had not been defined before.
And From the pattern E has already been defined at index 0 and index 4, Hence the final value for E in the bad match table should be E=7-4-1=2
The bad match table would look like.
E O L G *
2 5 3 1 7
That is from my understanding, correct me if am wrong.
Ma'am your should make more vidoes, your explanation is so good, The one and only video on youtube which explain Boyer Moore pattern Matching algorithm so nice and easy way, Tnq so much ma'am.........................................................................................

Nice explaining mam 👌
Thank you mam gud explanation keep going mam ❤
Nice explanation....
Thank You Mam. I was searching this topic for long.
Best explanation on this topic.
Mam very well explained, thank you so much.
Mam if a certain suffix is matched we use some different rule to update the index right?
Very clear explanation mam,thank you
you are the best
@bharathi Ramesh your explanation for Boyer Moore Pattern Matching algorithm is not working for this example,
txt = ababdabacdababcabab
pat = ababcabab
I believe it is because of the calculation of the bad match table, specifically the value of the last character,
in the bad match table, the value of the last character should be equal to the length of the pattern if it had not already been defined, as seen in your pattern b has already been defined
so instead of b=9, b=2.
After calculating the bad match table it should be
a b c *
1 2 4 9
Should we consider the space or not??
Awesome.. thankyou so much 😀
thankyou ma'am very nice explanation please upload more
The shaky camera and flickering light annoyed me and got dizzy. Make a video with a camera stand and good light. Your teaching method is amazing and easy to understand. Thank you.
tq mam its so helpful to me
easy to understand mam,thankyou mam
super explanation , mind blowing
Very well explained Ma'am
superb explanation
Amazing explanation... U should make more videos on algorithm concepts...
if multiple occurences of pattern in text is there will this work
nyc explanation mam
Very good explanation mam
Please make more videos
Thank you for such a good explanation
Good explanation. Thank you
Why isnt it working for strings "WELCOMETOCOLLEGE" and "COLLEGE"??
Because u included double quotes and question marks 😂😂
bestvideo! thank u ma'am
so, if the substring is COME, then will it be COME*? are we always going to add * at the end?
nice explanation mam.
Can you make more videos?
It will help us
Easily understandable.. Thank you so much mam.. But mam can you please make vedio on KMP matcher algorithm
really helpful
😍😍😍😍😍😍
Very good explanation ..
