Find the largest co-prime fraction less than the given fraction; Minimum count of numbers required ending with 7 to sum as a given number; Count 'd' digit positive integers with 0 as a digit; Find the closest Fraction to given fraction having minimum absolute difference; Extended Midy's theorem; Find all strings that match specific pattern. Solved 3 Linked list problems using Recursion and two-pointers approach: Flatten given Linked list; Rotate given Linked list; Clone a given Linked list with next and random pointers; Day 79. Given a binary tree, the task is to print the maximum sum of nodes of a sub-tree which is also a Binary Search Tree. If the sum of all three stacks is the same, then this is the maximum sum. For example in the given tree, maxSum Node = 4 with maximum sum of 28. The length of this cycle is 3, so 3 is returned.
