1601. Maximum Number of Achievable Transfer Requests

Leetcode Solutions

Initialize answer to 0 to store the maximum number of requests that can be considered.
Initialize an array indegree of size n with all values as 0 to track the net change in employee count for each building.
Define a recursive function that takes the current index of the request being considered and the count of requests included so far. a. If all requests have been considered, check if all values in indegree are zero. If so, update answer with the maximum of answer and count. b. If the current request is included, update indegree for the involved buildings and recursively call the function with the next index and count + 1. c. Backtrack by reverting changes in indegree. d. Recursively call the function with the next index without including the current request.
Return answer as the maximum number of achievable requests.
