Runtime: O(nlogn) — Sorting: As we know more than half of the array are elements of the same value, we can sort the array and all majority elements will be grouped into one contiguous chunk. Therefore, the middle (n/2th) element must also be the majority element. Average runtime: ...
Runtime:O(NlogN)- this is sorting time. Then we calculate recursion (memo) time, which is the number of times maxprofit() is called times the average time of maxprofit() function. The max times that we call maxprofit() function is2N, and the average time to execute the function isO(...
