The problem involves arranging coins in a staircase with specific row numbers, and the solution focuses on finding the maximum number of complete rows that can be built.
The solution involves analyzing the input (number of coins) and output (number of complete rows), and working through a simple approach using math to determine the complete rows.
To improve the solution further, simplifications can be made to optimize the algorithm, aiming for a faster runtime complexity close to square root of n.

Optimal solutions in coding interviews can impress interviewers and require O(1) time and space complexity.
In a coding problem like this one involving arranging coins in a staircase, understanding the complete rows and incomplete rows is key to solving it.
Preparation for coding interviews, like practicing on Leetcode, can help in tackling similar problems and improving problem-solving skills.
