Solution 1

The running time of the given code is O(n^2).

Here's why:

The outer loop runs n times, and for each iteration of the outer loop, the inner loop runs i times. In the worst-case scenario, i is equal to n. Therefore, the total number of operations is the sum of the first n integers, which is (n*(n+1 Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
