    #DidYouKnow:
    A permutation is used for list of data (where the order of the data matters) and the combination is used for a group of data (where the order of data doesn’t matter).

    whoever did not understand this read below
    let me ask you a question, if you are sitting on any of the 6 chairs arranged in circular, which particular chair are you sitting on
    most important in this is the word "ways"
    lets understand what is meant by "ways"
    one person wants to seat in a chair among six chairs arranged in straight line
    Q:what are different ways to do so?
    way 1: SNNNNN //he is sitting on 1st chair
    way 2: NSNNNN //he is sitting on 2nd chair
    way 3: NNSNNN //he is sitting on 3rd chair
    way 4: NNNSNN //he is sitting on 4th chair
    way 5: NNNNSN //he is sitting on 5th chair
    way 6: NNNNNS //he is sitting on 6th chair
    Ans: so there are 6 different ways he can sit on a chair.
    now when it comes to circular arrangement of chair
    what are different ways a person can seat on a chair?
    way 1: SNNNNN /he is sitting on 1st chair
    way 2: SNNNNN /he is sitting on 1st chair
    way 3: SNNNNN /he is sitting on 1st chair
    way 4: SNNNNN /he is sitting on 1st chair
    way 5: SNNNNN /he is sitting on 1st chair
    way 6: SNNNNN /he is sitting on 1st chair
    confused right, circle does not have a starting point,the thing is whenever that person chooses a chair and seats on it,that particular chair itself is the first chair thats why its always going to be "SNNNNN" which is the only one "unique" way that he can sit.
    ans: one way
    conclusion: in linear arrangement of chairs whenever a person sits on a particular chair his chair is being referenced from the first chair eg. he is sitting on 3rd chair or he is siting on 5th chair this way we have 6 different ways
    # but in circular arrangement whichever chair he sits on is the first chair itself bcz there is no start point in circle for reference to say that he is sitting on 3rd chair or 4th chair and so on.

      Lemme make u understand the reason.
      Consider 3 men ( a,b,c)... How they can be seated in a circular table?
      3! (No, Lmme show you those arrangements and why not 3!)

    Another way you can think of it as that there are 6! ways to be seated. However, in that arrangement, if you shift everyone 1 place to the left, the arrangement still appears the same. You can do this a total of 6 times before the arrangement goes back to the original spot.
    That's just how I thought of it but the method in this video is definitely easier to understand.

    When you sit on the second chair or the first chair or any of the 6 chairs the veiw is the same, no matter on which chair you sit it is the same condition. Another way of thinking is that you have 6 identical toys if you pick/choose (combination) any one the toys then it is the same way as they are the same.
