I want to find the maximum sum in a 2D matrix such that: You can pick only 1 element from each row You cannot pick a column that has been picked before. Example: matrix = [ [12, 1, 1, 1], [13, 10, 1, 1], [40, 1, 1, 12] ] Solution: We pick 12 from 1st row Now w...

Clearly, if all the input numbers had a different length, the problem would have a trivial solution: just iterate over the input numbers in decreasing order by length, choosing each number if and only if XORing it with the maximum so far increases the maximum, i.e., if and only if its...
