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 x=0,y=0;
    int i;
    for(i=0;i<8;i++){
    x<<=1;
    x|=((val>>(i*2))&1);
    
    }
    x&=0xFF;//8 bit to ensure
   for(i=0;i<8;i++){
          y=y<<1;
          y|=(x&1);
          x=x>>1;

    }
    return y;
}

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

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