Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    uint8_t out = 0 ; 
    for(int i = 14 ; i > 0 ; i= i-2 )
    {  
        out |= ((val >> i) & 1);
        out <<= 1;
    }
    out |= ((val) & 1);
    return out;
}

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

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