[LeetCode]Remove Element

class Solution {public:int removeElement(int A[], int n, int elem) {// Start typing your C/C++ solution below// DO NOT write int main() functionint len = 0;for (int i = 0; i < n; ++i){if (A[i] != elem)A[len++] = A[i];}return len;}};

second time

class Solution {public:int removeElement(int A[], int n, int elem) {// Start typing your C/C++ solution below// DO NOT write int main() functionint curIdx = 0;for(int i = 0; i < n; ++i){if(A[i] != elem) A[curIdx++] = A[i];}return curIdx;}};
