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 mask = 1U;
    uint16_t result = 0U;
    for(uint16_t i=0;i<8;i++){
        result |= ((((uint16_t)val)>>i) & mask) << (2*i);
      
    }
    return result;
}

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

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