Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    uint16_t rslt;
    for (int i=0;i<32;i+=2){
        if (((1<<i) & val)!=0){
            rslt|=(1<<i/2);
        }
    }
    return rslt;
}

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

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