but i discovered the input actually has values zero for N and L!!an integer L, which is the number of lollies available on that day ( 1 <= L <=100),
an integer N, which is the associated delay ( 1 <= N <= 100).
I`m pretty sure about this because i told my program to terminate if it found a L or N were equal to zero,and my program run for 0.002, when it run in 0.230 without this exception. I handle those especial cases and finally got accepted( after nearly 30 "wrong" submissions).
So i woul like to ask administrators to correct the input, or to modify the statement, so people don't waist their time wondering what's wrong in vane.(My suggestion would be to eliminate the zero inputs, cause they got no sense, in my humble opinion).
