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 mask = 0x01;
    uint8_t req_digit;
    uint8_t reg = 0;
    

    for(int i=0;i<8;i++){

        req_digit = val & mask;

        reg |= (req_digit<<(i));

        val = val >> 2;

    }

    return reg;
}

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

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