#include <stdio.h>

unsigned char modifyBit(unsigned char reg, int pos, int mode) {

// Write your code here

if(mode==1)

reg=reg|(1<<pos);

else

reg=(reg)&(~(1<<pos));

return reg;

}

int main() {

unsigned char reg;

int pos, mode;

scanf("%hhu %d %d", &reg, &pos, &mode);

printf("%d", modifyBit(reg, pos, mode));

return 0;

}
