Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    uint16_t temp = 0;
    for(int i = 0; i<8;i++){
        temp |= ((val >> (2*i))&0x1)<<i;
    }
    return temp;
}

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

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