Leetcode c语言-Remove Element

Title:

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.


这道题非常简单,与上题思路类似,不多赘述。


Solution:

int removeElement(int* nums, int numsSize, int val) {
    int len=0;
    int i;
    
    for (i=0;i<numsSize;i++) {
        if (nums[i]!=val) {
            nums[len]=nums[i];
            len++;
        }
    }
    return len;
}
