LeetCode027. Remove Element C语言

Given an array and a value, remove all instances of that value in place and return the new length.
Do not allocate extra space for another array, you must do this in place with constant memory.
The order of elements can be changed. It doesn‘t matter what you leave beyond the new length.
Example:
Given input array nums = [3,2,2,3], val = 3
Your function should return length = 2, with the first two elements of nums being 2.

题意：给一个数组，再给你一个数val，从数组中把val删掉并返回剩余数组的长度

int removeElement(int* nums, int numsSize, int val) {
    int i=0;
    int j=0;
    //这个就跟那个26题去重一个思想了
    for(j=0;j<numsSize;j++){
        if(nums[j]!=val){
            nums[i++]=nums[j];
        }
    }
    return i;
}

PS:这个跟之前的26题一样，双指针，，，，，
