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 = 0;
    uint8_t mask = 1 << 7;
    for(int i = 0;i < 8 ;i ++){
         result <<= 2;
        result += (val & mask)>> 7-i;
       
        mask >>= 1;
    }
    return result;
}

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

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