  * @brief
  * Reduced all possibilities of a number which cannot be prime.
  * Eg: No even number, except 2 can be a prime number, hence we will increment
- * our loop with i+6 jumping and check for i or i+2 to be a factor of the number;
- * if it's a factor then we will return false otherwise true after the loop terminates at the terminating condition which is (i*i<=num)
