算法学习--冒泡排序与选择排序

仅用来记录算法学习笔记，纯手打，不喜勿喷

冒泡排序

//冒泡排序

    NSMutableArray *array = [NSMutableArray arrayWithArray:@[@"6",@"5",@"4",@"3",@"2",@"1",@"0"]] ;
    for (int x = 0; x [array[i+1] intValue]) {
                j = array[i];
                array[i] = array[i+1];
                array[i+1] = j;
            }
        }
    }
NSLog(@"array==%@",array);

输出结果为

2020-04-16 10:29:42.577734+0800 KaadasLock[2940:636672] array==(
    0,
    1,
    2,
    3,
    4,
    5,
    6
)

选择排序法

    NSMutableArray *arrays = [NSMutableArray arrayWithArray:@[@"6",@"5",@"4",@"3",@"2",@"1",@"0"]];
    for (int j = 0; j [arrays[i] intValue]) {
                x= i;
            }
            id tmp = arrays[j];
            arrays[j] = arrays[x];
            arrays[x] = tmp;
        }
    }
    NSLog(@"arrays[] ===%@",arrays);

输出结果为

2020-04-16 19:13:52.560757+0800 ALPHA LOCK ACCESS[3518:789724] arrays[] ===(
    0,
    1,
    2,
    3,
    4,
    5,
    6
)
