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
    uint16_t temp=0;
    for(int i=15;i>=0;i--)
    {
        if(reg & (1<<i))      
       {
        temp |= (1<<i);
        break; 
       } 
       

    }
    
    return temp;
}

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

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