2 OA question. One is by chair. One is Given two arrays where array 'a' is fixed and array 'b' can be rearranged, for example a: 1,2,3,4,5 and b: 2,6,4,3,5. The objective is to rearrange array 'b' in such a way that as many numbers in 'b' as possible are greater than their corresponding numbers in 'a'. Finally, the sum of numbers in 'b' that are greater than the corresponding numbers in 'a' is calculated. For example, if a: 1,2,3,4,5 and b: 2,3,4,5,6 -> return 2+3+4+5+6.
