Bit Reversal in an 8-bit Value

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

uint8_t reverse_bits(uint8_t val) {
    // Your logic here
    int out = 0;
    for(int i=0; i<4; i++){
        uint8_t least = val>>(7-i) &1;
        uint8_t most = val<<(7-i)&1U<<(7);
        out|=((least<<i)|(most>>(i)));
        }
    return out;
}

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

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