Program to get minimum number of coins.
Create an array of coin denominations
Sort the array in descending order
Loop through the array and subtract the highest denomination possible

- Q3. Logic for a program to sort an array in which we have an array of infinite length but contains only three elements like -1, 0,1.
- Ans.
Sorting an array of infinite length with only three elements (-1, 0, 1)
Use counting sort algorithm to count the frequency of each element
Create a new array with sorted elements based on their frequency
Time complexity is O(n) and space complexity is O(1)
Example: [-1, 1, 0, 1, -1, 0, 1, -1, 0, 1, ...]

Check if the maximum value in the left subtree is less than the root and the minimum value in the right subtree is greater than the root.
Use recursion to check if all subtrees are BSTs.
Time complexity: O(n), Space complexity: O(h) where h is the height of the tree.
- Q3. Find pair in BST with given sum
- Ans.
Given a BST and a sum, find a pair of nodes whose values add up to the given sum.
Traverse the BST in-order and store the nodes in a list
Use two pointers approach to find the pair with the given sum
If the sum is less than the current pair, move the right pointer to the left
If the sum is greater than the current pair, move the left pointer to the right
If the sum is equal to the current pair, return the pair
