Bit Reversal in an 8-bit Value

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

uint8_t reverse_bits(uint8_t val) {
    // Your logic here
    uint8_t result = 0;
    int i=7 ;
    while(val){
        if(val & 1u){
            result |= (1u << i);
        }
        val >>= 1;
        i--;
    }


    return result;
}

int main() {
    uint8_t val;
    scanf("%hhu", &val);

    uint8_t result = reverse_bits(val);
    printf("%u", result);
    return 0;
}
