Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    // Your logic here

    uint8_t result = 0;
    uint16_t mask = 1U;
    for(int i = 0; i< 8; i++){
        result |= (mask & val) >> i;
        mask = mask << 2;
    }
    return result ;
}

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

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