Compress Interleaved Bits Reverse Bit Spreading

Code

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

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

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

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