[数据结构]合并有序数组

###JAVA版
~~~
public class Merge {
//合并有序数组
public static void mergeSort(int a[], int b[], int c[]) {
int n = a.length, m = b.length;
int i, j, k;
i = j = k = 0;
while (i < n && j < m) {
if (a[i] < b[j]) {
c[k++] = a[i++];
} else {
c[k++] = b[j++];
}
}
while (i < n)
c[k++] = a[i++];
while (j < m)
c[k++] = b[j++];
}
//打印数组中的元素
public static void printArr(int a[]) {
for (int i = 0; i < a.length; i++) {
System.out.print(a[i] + "\t");
}
}
public static void main(String[] args) {
System.out.println("Hello World!");
int[] a = new int[] { 1, 2, 5, 6 };
int[] b = new int[] { 3, 8, 9, 10 };
int c[] = new int[8];
mergeSort(a, b, c);
printArr(c);
}
}
输出结果：
1 2 3 5 6 8 9 10

###C语言版
~~~
#include <stdio.h>
// 打印数组a
void printArr(int a[],int n){
for (int i = 0; i < n; ++i)
{
printf("%d\t",a[i]);
}
printf("\n");
}
//合并有序数组
void mergeArray(int a[],int n,int b[],int m,int c[]){
int i, j, k;
i = j = k = 0;
while (i <n && j<m)
{
if (a[i] < b[j])
c[k++] = a[i++];
else
c[k++] = b[j++];
}
while (i < n)
c[k++] = a[i++];
while (j < m)
c[k++] = b[j++];
}
int main(){
int a[3]={2,3,6};
int b[2]={1,5};
int c[5]={};
mergeArray(a,3,b,2,c);
printArr(c,5);
}
输出结果：
yaopans-MacBook-Pro:algorithm yaopan$ ./a.out
1 2 3 5 6
