2) Second question was of 5 marks and in that a binary tree was given and we need to complete a function such that the function accepts the root node and in function we need to find GCD of each pair of siblings and then find the maximum and minimum value of GCD. In the end we need to return the difference b/w maximum and minimum GCD Values.

3) Third question was also of 5 marks and it was the slight modification of the question – Letter Combination of a Phone Number (Present on GFG).
