88.合并两个有序数组

Golang语法不支持while循环，自增不能当表达式使用，所以用它写这道题看起来很丑

func merge(a []int, m int, b []int, n int) []int{
    tmp := make([]int, m+n)
    i, j, k := 0, 0, 0
    for i < m && j < n {
        if a[i] < b[j] {
            tmp[k] = a[i]
            k++
            i++
        } else {
            tmp[k] = b[j]
            k++
            j++
        }
    }
    for i < m {
        tmp[k] = a[i]
        k++
        i++
    }
    for j < n {
        tmp[k] = b[j]
        k++
        j++
    }

    for k := 0; k< m+n;k++ {
        a[k] = tmp[k]
    }
    return a
}

这道题用Java写，看起来就比较优雅

class Solution {
    public void merge(int[] nums1, int m, int[] nums2, int n) {
        int[] tmp = new int[m + n];
        int i,j,k;
        i = j = k = 0;
        while(i < m && j < n){
            if(nums1[i] <= nums2[j]){
                tmp[k++] = nums1[i++];
            }else{
                tmp[k++] = nums2[j++];
            }
        }
        while(i < m) tmp[k++] = nums1[i++];
        while(j < n) tmp[k++] = nums2[j++];
        for(k = 0;k < (m+n); k++){
            nums1[k] = tmp[k];
        }
    }
}
