HackerEarth Equal Division problem solution YASH PAL, 31 July 202415 February 2026 In this HackerEarth Equal Division problem solution, There are N teams in a software company. The ith team has Bi employees in it and a total budget of units of money. Each team has to divide their budget within their employees equally. But for some teams, it’s not possible to divide the budget equally.Therefore, the company have to perform revisions in the teams’ budget sizes. In one revision, to revise the budget of ith team, the budget of the first i teams has to be increased by 1. Your task is to find the minimum number of revisions needed so that for each team, equal distribution of their budget among the employees is possible.
