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 num = 0;
    for(int i=0; i<16; i++){
        if(val>>i&1)                    // checking the bit is set
        num |= (((val>>i)&1)<<i*2);     // right shifting and inserting the set bit
    }
    return num;
}

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

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

Solving Approach

uint16_t spread_bits(uint8_t val) {

    // Your logic here

    uint16_t num = 0;

    for(int i=0; i<16; i++){

        if(val>>i&1)                    // checking the bit is set

        num |= (((val>>i)&1)<<i*2);     // right shifting and inserting the set bit

    }

    return num;

}
