Min Number of coins for change This solution aims to solve the "minimum number of coins for change" problem, which is a classic dynamic programming problem in computer science. The pr…
This solution seeks to solve the problem of finding the number of ways to make change for a given amount of money n using a given set of coin denominations denoms. First, here is a representation …
The solution implements three different depth-first traversal methods for binary trees: in-order traversal, pre-order traversal, and post-order traversal. These traversal methods visit each node i…
Inverting a Binary Tree This solution herein is expected to solve the problem of inverting a binary tree. In other words, it aims to transform a binary tree such that for every node, its left c…
Validate BST Validate BST aims to determine whether a given binary tree is a valid binary search tree (BST). A BST is a binary tree where each node's value is greater than all values in its…
Permutations refer to all possible arrangements of elements within a sequence, where the order of elements matters. Permutations can be generated for a list, tuple, or any iterable object. Python …
A binary search tree is a hierarchical data structure that allows for efficient insertion, deletion, and searching of elements. The solution below defines a Binary Search Tree (BST) class and its …
Tail Recursion Tail recursion is a type of recursive function where the last statement executed within the function is a recursive call. Nothing remains to be executed after the recursive call. …
The given solution implements the Insertion Sort algorithm, which is a simple comparison-based sorting algorithm. What is the Problem Being Solved? The problem being solved is sorting an arra…
The solution below implements the Selection Sort algorithm, which is a simple comparison-based sorting algorithm. def selection_sort(array): i = 0 while i < len(array): smallest=i f…
