Bit Spreading Interleave Bits with Zeros

Code

#include <stdio.h>
#include <stdint.h>

uint16_t spread_bits(uint8_t val) {
    // Your logic here
   /* uint16_t result = 0;
    for (int i = 0; i< 8; i++){
        if(val & (1 << i)){
            result |= (1 << 2*i);
        }
    }*/
     uint16_t result = val;
     result =(result| (result<<4)) & 0x0F0F;
     result = (result |(result<<2)) & 0x3333;
     result = (result |(result<<1)) & 0x5555;

    return result;
}

int main() {
    uint8_t val;
    scanf("%hhu", &val);

    uint16_t result = spread_bits(val);
    printf("%u", result);
    return 0;
}
