88. Merge Sorted Array

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 nums1 and nums2 are m and n respectively.

class Solution {
public:
    void merge(vector& nums1, int m, vector& nums2, int n) {
        vector t = vector(nums1);
        nums1.resize(m+n);
        int p1 = 0, p2 = 0;
        while(p1 < m && p2 < n){
            if(t[p1] < nums2[p2]){
                nums1[p1+p2] = t[p1++];
            }else{
                nums1[p1+p2] = nums2[p2++];
            }
        }
