The elements of array must already be sorted in increasing value according to the sort order defined by the IComparable<T> implementation; otherwise, the result might be incorrect. Duplicate elements are allowed. If the Array contains more than one element equal to value, the method returns the...

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