Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array A = [1,1,2], Your function should retur...
Follow up for "Remove Duplicates": What if duplicates are allowed at mosttwice? For example, Given sorted arraynums=[1,1,1,2,2,3], Your function should return length =5, with the first five elements ofnumsbeing1,1,2,2and3. It doesn't matter what you leave beyond the new length. ...
