复制 #include <stdio.h> void josephus(int n, int p) { int people[n]; for (int i = 0; i < n; i++) { people[i] = i + 1; } int count = 0; int index = 0; int countOut = 0; while (countOut < n) { if (people[index] != 0) { count++; if (count == p) { printf("%d ", people[index]); people[index] = 0; countOut++; count = 0; } } index = (index + 1) % n; } printf("\n"); } int main() { int n, p; scanf("%d %d", &n, &p); josephus(n, p); return 0; }请把这段代码修改为输出时行尾无空格

修改后的代码如下：

#include <stdio.h> 

void josephus(int n, int p) {
    int people[n];
    for (int i = 0; i < n; i++) {
        people[i] = i + 1;
    }

    int count = 0;
    int index = 0;
    int countOut = 0;

    while (countOut < n) {
        if (people[index] != 0) {
            count++;
            if (count == p) {
                printf("%d", people[index]);
                people[index] = 0;
                countOut++;
                count = 0;
                if (countOut != n) {
                    printf(" ");
                }
            }
        }
        index = (index + 1) % n;
    }
    printf("\n");
}

int main() {
    int n, p;
    scanf("%d %d", &n, &p);

    josephus(n, p);

    return 0;
}

主要的修改在 `josephus` 函数中的输出部分，当输出一个数时，先判断是不是最后一个数，如果不是，再输出一个空格。这样就能保证行尾无空格。
