选择排序代码

#include <iostream>
using namespace std;

void SelectSort(int32_t numList[], int32_t len) {
    for (auto i = 0; i < len; i++) {
        auto min = i; //标记最新数的下标
        for (auto j = i + 1; j < len; j++) {
            if (numList[min] > numList[j]) {
                //找到更小的数,记录下标
                min = j;
            }
        }

        auto tmp = numList[i];
        numList[i] = numList[min];
        numList[min] = tmp;
    }
}

void main() {
    int32_t numList[] = { 31, 41, 59, 26, 41, 58, 12 };
    int32_t count = sizeof(numList) / sizeof(numList[0]);
    SelectSort(numList, count);


    for (auto num : numList) {
        std::cout << num << " ";
    }
    std::cout << std::endl;
}
