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...
Few simple examples to find or count the duplicates in stream and remove the duplicates from stream in Java 8. We will use ArrayList to provide stream of elements including duplicates. Few simple examples to find and count the duplicates in aStreamand remove those duplicates sinceJava 8. We w...

Given a sorted array nums, 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 by modifying the input array in-place with O(1) extra memory. ...
Follow up for "Remove Duplicates": What if duplicates are allowed at mosttwice? For example, Given sorted array A =[1,1,1,2,2,3], Your function should return length =5, and A is now[1,1,2,2,3]. 题解: 之前是不允许有重复的。
