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 v = val;
    v = (v | (v << 4)) & 0x0F0F;
    v = (v | (v << 2)) & 0x3333;
    v = (v | (v << 1)) & 0x5555;
    // val =(uint16_t) val;
    // val = (val | (val << 4)) & 0x0F0F;
    // val = (val | (val << 2)) & 0x3333;
    // val = (val | (val << 1)) & 0x5555;
    return v;
}

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

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