Now, check if the maximum difference is between ith and maximum element, store it in variable diff. Let this index be max_index, return max_index + min.Above solution requires O(max-min+1) extra space. (Ofcourse, that comes that cost of readability), Below is a solution without use of sort. This doesn't pass the same 7 test cases that are failing for OP. and this approach takes him to write this page. One extremely powerful typescript feature is automatic type narrowing based on control flow. A tag already exists with the provided branch name. . Leftmost Column with at Least a One, LeetCode 1570.
