Given an array and a value, remove all instances of that value in place and return the new length.
The order of elements can be changed. It doesn't matter what you leave beyond the new length.
#include<iostream> #include<vector> using namespace std; int removeElement(int A[], int n, int elem) { int newlength = 0; for (int i = 0; i < n;++i) { if (A[i] != elem) { A[newlength] = A[i]; newlength++; } } return newlength; }
