How to find the triplet numbers from an array whose sum is divisible by 9 using stream
This is the third solution to find the triplets of numbers in which their sum is divisible by 9 from an array of integers. This method uses three nested IntStream to traverse array, add any three numbers come across in each iteration, and then uses simple predicate to verify that the sum is divisible by…
