Ans. 
Check if a given array contains a valid triplet where two elements sum up to the third.
• Iterate through all possible triplets in the array and check if any of the conditions are satisfied.

• Use nested loops to compare each element with every other element in the array.

• Handle cases where the elements are not distinct by ensuring i != j, j != k, and i != k.
