Merge Sorted Array
Desicription
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.
Solution
代码语言：javascript复制class Solution {
public:
void merge(vector<int>& nums1, int m, vector<int>& nums2, int n) {
int tol = m n - 1;
m--;
n--;
while(n >= 0)
nums1[tol--] = (m >= 0 && nums1[m] > nums2[n]) ? nums1[m--] : nums2[n--];
}
};
