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 res = 0;

    for(int i = 0;i<8;i++){

        res |= (((val>>i) & 1) << (2*i));


    }

    return res;

}

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

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