Bouncing Ball

CodeChefOpen on judge ↗

Consider infinite well bounded by lines x=0 and x=n. A ball starts bouncing from origin x=0 taking step of size 1 in 1st second, step of size 2 in 2nd second, ... step of size k in kth second. When it reaches any of wall it reflects back. For example consider a well bounded by x=0 and x=9. After 1 second ball will be at x=1, similarily ball will be at x=3, x=6, x=8, ... after t=2, t=3, t=4... sec
