How to find the triplet numbers from an array whose sum is divisible by 9
This is the second solution to find the triplets of numbers in which their sum is divisible by 9 from an array of integers. This method uses the core logic of traversing array using 3 nested for loops, add any three numbers come across in each iteration, and then uses simple predicate to verify that…

How to find the pairs of numbers from an array whose sum is divisible by 9
This is the second solution to find the pairs of numbers in which their sum is divisible by 9 from an array of integers. This method uses the core logic of traversing array using nested for loops, add any two numbers come across in each iteration, and then uses a simple predicate to verify that…

How to check whether a given integer is prime number or not
This is the second solution to find whether the given integer number is prime or not using a simple predicate and another core logic that no number is divisible by more than half of itself.
