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 = 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;
}
