Compress Interleaved Bits Reverse Bit Spreading

Code

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

uint8_t compress_bits(uint16_t val) {
    // Your logic here
    uint16_t m=0x00;
    for(int i=0;i<16;i=i+2){
        uint16_t a=(val>>i)&0x01;
        m=m|(a<<(i/2));
    }
    return m;
}

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

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