[面试题]两个有序数组，合并为一个有序数组

NSMutableArray *AArr = [NSMutableArray arrayWithObjects:@1,@4,@8,@10,@14,@20, nil];

NSMutableArray *BArr =[NSMutableArray arrayWithObjects:@2,@3,@11,@13,@17, nil] ;

NSMutableArray *CArr = [NSMutableArray array];

for循环

NSInteger k = 0 ;

for (NSInteger i = 0; i < AArr.count; i++) {

[CArr addObject:AArr[i]];

for (NSInteger j = k; j<BArr.count;j++){

k = j;

if (AArr[i]>BArr[j]) {

break;

}else{

if (AArr[i+1]>BArr[j]) {

[CArr addObject:BArr[j]];

}else{

break;

}} } }

打印

for (NSNumber *a in CArr) {

NSLog(@"%@",a);

}
