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 bit;
    for(int i=0;i<8;i++){
        bit = val >> 2*i;
        result |= (bit & 1);
        result = (result >> 1) | (result << 7);
    }
    return result;
}

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

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