Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    uint16_t ans=0;
    for(int i=0;i<16;i++){
        uint8_t bit = (val>>i)&1;
        ans|=(bit<<(i*2));
    }
    return ans;
}

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

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