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 num = val;

    num = (num | (num<<4))&0X0F0F;
    num = (num | (num<<2))&0x3333;

    num = (num | (num<<1))&0x5555;


    return num;
}

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

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