Array size comparison rules:
According to the string comparison rules:
1. The two arrays are equal in length: sequentially comparing array elements, determines a large element of the large array;
2. The two arrays unequal length: sequentially comparing array elements, determines the large array of large elements, if a small length of all elements of the array and comparing the array length End length equal to the number of groups is determined that a large number of head;
public static int[] large(int[] a,int[] b){
if (a.length==0&&b.length!=0)
return b;
if(b.length==0&&a.length!=0)
return a;
if(a.length!=0&&b.length!=0){
int m=a.length;
int n=b.length;
int k=(m>n)? m:n;
for(int i=0;i<k;i++){
if(a[i]>b[i]){
retunrn a;
}else
if(a[i]<b[i]){
return b;
}else if(a[i]==b[i]){
i++;
}
}
}
