# Leetcode Biweekly Contest 37

in #codeonsteemlast month

I have recently started to attend the online coding contest. Leetcode has held weekly contests on Sunday early mornings - which isn't ideal for coders living in Europe.

However, they have biweekly contests, which is run the Sat 3:30 to 5:30 (BST) every two weeks.

Today's contest: https://leetcode.com/contest/biweekly-contest-37

Today's contest difficulty - considered to be medium/high. I have solved 2 out of 4 - the third one WA and the last one Time Limited Exceeded.

The programming language I choose is C++. I have quite many wrong answers or Time Limit Exceeded - which adds a lot of time penalization to the final result.
