Bit Reversal in an 8-bit Value

Code

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

uint8_t reverse_bits(uint8_t val) {
    // Your logic here
    val = ((val & 0xF0)>>4) | ((val & 0x0F)<<4); //swap nibbles
    val = ((val & 0xCC)>>2) | ((val & 0x33)<<2);
    val = ((val & 0xAA)>>1) | ((val & 0x55)<<1);

    return val;
}

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

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