Keep Only the Highest Set Bit

Code

#include <stdio.h>
#include <stdint.h>

// Complete the function
uint16_t highest_set_bit(uint16_t reg) {
    // Your logic here
    int data=reg;
    int flag=0;
    for(int bit=15;bit>=0;bit--){
        if((data>>bit)&1==1){
            if(!flag){
                flag=1;
                continue;
            }
            else data &=~(1<<bit);
        }
    }
    return data;
}

int main() {
    uint16_t reg;
    scanf("%hu", &reg);

    uint16_t result = highest_set_bit(reg);
    printf("%hu", result);
    return 0;
}
