Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val){
    uint16_t result = 0;
    for(int i = 0; i< 8; i++){
        result |= ((val >> (2 * i)) & 1) << i;
    }
    return result;
}

int main() {
    uint16_t val;
    scanf("%hu", &val);
    printf("%u", compress_bits(val));
    return 0;
}
