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

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

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