find duplicates in array

Given an array of integers, 1≤a[i]≤ n (n = size of array), some elements appear twice and others AppE AR once.Find all the elements, appear twice in this array.Could do it without extra space and in O (n)

Given an array of integers, 1≤a[i]≤ n (n = size of array), some elements appear twice and others AppE AR once.Find all the elements, appear twice in this array.Could do it without extra space and in O (n)

These two questions are interesting, because the elements are 1~n, so the value of each element-1 (mapped to 0~n-1) can be directly used as subscript. This will be nums in the corresponding subscript element *-1 with I means index+1 this element has

Title DescriptionGiven a sorted array, you need to Delete the repeating element in place so that each element appears up to two times, returning the new length of the array after it is removed.Instead of using extra array space, you must modify the
