Array coins

Similar Problems:

You have a total of n coins that you want to form in a staircase shape, where every k-th row must have exactly k coins.

Given n, find the total number of full staircase rows that can be formed.

n is a non-negative integer and fits within the range of a 32-bit signed integer.

Example 1: n = 5 The coins can form the following rows: * * * * * Because the 3rd row is incomplete, we return 2.

Example 2: n = 8 The coins can form the following rows: * * * * * * * * Because the 4th row is incomplete, we return 3.
