Find a triplet that sum to a given value | returns true if there is triplet with sum equal to ' sum ' present in A [ ] . Also , prints the triplet.
Sort the elements.
Now fix the first element one by one and find the other two elements.
To find the other two elements , start two index variables from two corners of the array and move them toward each other index of the first element in the remaining elements.
index of the last element.
A [ i ] + A [ l ] + A [ r ] > sum.
If we reach here , then no triplet was found.
