Can someone post the problems?

I don’t remember the remember the questions properly but here goes the questions-

  1. You are given n numbers, you need to tell how many ways you can choose 4 numbers out of them so that its sum is T.
  2. Very Long Question. Can’t explain in this answer
  3. Forgot
  4. You are given a binary string, you need to tell the number of ways you can drop some strings so that you can get the string 0011 or 00110011 or 001100110011.

I’ll provide you the questions as soon as I get it.
Happy Coding.

Lol, you’re getting 50-55 and that’s a pretty amazing score for a class 8 student. So far, max cut off for class 8 students has been in the 25-45 range. So chill, you will qualify.
