#include <string.h>

void del(char s[], int i, int num) {
    int len = strlen(s);
    int j;
    for (j = i-1; j < len - num; j++) {
        s[j] = s[j + num];
    }
    s[len - num] = '\0';
}

int main() {
    char s[50];
    scanf("%s", s);

    int i, num;
    scanf("%d %d", &i, &num);

    del(s, i, num);

    printf("%s\n", s);

    return 0;
