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 compressed_result=0;
    for(int i=0; i<8; i++){
        uint16_t bit = val & (1 << (2*i));
        compressed_result |= (bit >> i);
    }
    return compressed_result;
}

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

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