Question:http://codeforces.com/contest/990/problem/E

help me with the placing of the lamps. I have thought about an approach but it has O(n2) time complexity, one for loop to iterate 1-k and the other one for placing the lamps int their correct position, so that the whole street is lighted. But the process is a bit messy.

Please tell me how to solve the problem.
