HackerEarth Pro and Con List problem solution YASH PAL, 31 July 202415 February 2026 In this HackerEarth Pro and Con List problem solution, There is a long list of n girls in front of Barney, and he is to calculate the optimal “happiness” he can find by selecting exactly 2 girls. (Why 2? No one knows!) Ted, as a fan of pros and cons, suggests to make a list, a method for estimating the maximum happiness that Barney can achieve. Each girl is characterized by two parameters: – favour: if this girl is chosen, his happiness increases by this amount.– anger: if this girl is not chosen, his happiness decreases by this amount. Find the maximum “happiness” that Barney can obtain. Note that the answer is allowed to be negative.
