Compress Interleaved Bits Reverse Bit Spreading

Code

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

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

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

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