Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.

Note:
You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. The number of elements initialized in nums1and nums2 are m and n respectively.

 

public class Solution {
    public void merge(int[] nums1, int m, int[] nums2, int n) {
        while (m > 0 && n > 0) {
        	if (nums1[m-1] > nums2[n-1]) {
        		nums1[m+n-1] = nums1[m-1];
        		m--;
        	} else {
        		nums1[m+n-1] = nums2[n-1];
        		n--;
        	}
        }
        while (n > 0) {
        	nums1[m+n-1] = nums2[n-1];
        	n--;
        }
    }
}
