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 count =0;
    for (int i = 0;i < 16;i++){
        if(reg & (1<<i)){
            count = i;
        }
    }
    for(int j= 0;j< count ; j++){
        reg &= ~(1<<j);
    }
    return reg;
}

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

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