Great Explanation 💯🔥
Earlier I thought of finding permutations of p's and storing in hashmap and then just iterating over the anagram string..

[@ecs185_shaileshbharti3]

Here will the Space complexity be O(1) !!
I meant we are using an answer vector na so that way ...?
Those two freq and window vector have constant space but the ans vector!!

[@AyushiSharmaDSA]

yes, but the output vector or string we have, that we do not consider as extra space :), because that is anyway needed, any extra data structure we use for solution, that we consider in space complexity :)

Hi, sure :)

Thank you di

Welcome Ishaan, glad it was helpful :)

[@sakshamsengar9798]

if u r comparing vectors in each step its complexity would be o(k) so overall complexity will be o(n*k).also the space complexity is not constant its o(n).because u r using the extra array

[@AyushiSharmaDSA]

Hi , size of vector is 26 and space complexity will be constant as vector size will be 26

[@sakshamsengar9798]

@@AyushiSharmaDSA u r right size is small so it wont matter here

[@parthratra5768]

superb explanation 🙌🙌🥳🥳di can u plz make a video on sum of two arrays

[@AyushiSharmaDSA]

Sure Parth :) can you share the problem link

Please solve Set Matrix Zeroes leetcode problem

Sure :)

[@VishnuYadav-so5yv]

How many questions to do per topic??

[@AyushiSharmaDSA]

Hi Vishnu, nothing as such, just start with easy practice around(10-15) and then you can do medium problems.

[@VishnuYadav-so5yv]

@@AyushiSharmaDSA as a beginner, can I start watching your arrays vedio

[@AyushiSharmaDSA]

@@VishnuYadav-so5yv no, I would suggest first get familiar with every data structure like if you want to use hashmap then which library you will use, like that. Then when you know each and every data structure, you can start practicing different problems :)

[@VishnuYadav-so5yv]

Last line not cleared
i -len+1

[@ecs185_shaileshbharti3]

Dry run the code bro ,you will get it...
Since you have to return the starting index that's why we are substracting the Length bcz in loop we are iterating after the window size

[@AyushiSharmaDSA]

Yes Pratyush, dry run once and let me know if it's not clear then :)

[@invincible_5956]

can any please check my code it giving 0 as answer always
int search(string pat, string txt) {
int p[26]={0};int t[26]={0};
const char *s = pat.c_str(); int len=0;
while (*s)
{
p[*s-'a']++;
s++; len++;
}
int count=0; int flag=1;
const char *x = txt.c_str(); int lent=0; const char *first = txt.c_str();
while(*x)
{
t[*x-'a']++;

if(lent>=len) { flag=1;
for(int row=0;row
