And, it is updated when i start solving problem.
Problem 1. Choose a number ( O )
A XOR A XOR A XOR = A
Problem 2. Favorite Number ( O )
When participants get high points in the order of low points, the highest point among these points is the minimum score required to win. So, all participant point + high point value(A) compare the minimum score required to win(B). And if A >= B, this participant can win.
Problem 3. Test Study ( O ) ( Very easy )
This problem simple. Sort scores ascending or descending. type ascending = add the K number of elements from the end type descending = add the K number of elements from the first
Problem 4. Dart Game ( O )
I get angle use the arctan and get index using round.
