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 out = 0;
    for (int i = 0; i < 8; ++i) {
        if (val & (1u << i)) {          // if the i-th bit is 1
            out |= (1u << (2 * i));     // set the (2*i)-th bit in output
        }
    }
    return out;
}


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

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