**String Validators Python**

### Problem Statement :

Python has built-in string validation methods for basic data. It can check if a string is composed of alphabetical characters, alphanumeric characters, digits, etc. str.isalnum() This method checks if all the characters of a string are alphanumeric (a-z, A-Z and 0-9). >>> print 'ab123'.isalnum() True >>> print 'ab123#'.isalnum() False str.isalpha() This method checks if all the characters of a string are alphabetical (a-z and A-Z). >>> print 'abcD'.isalpha() True >>> print 'abcd1'.isalpha() False str.isdigit() This method checks if all the characters of a string are digits (0-9). >>> print '1234'.isdigit() True >>> print '123edsd'.isdigit() False str.islower() This method checks if all the characters of a string are lowercase characters (a-z). >>> print 'abcd123#'.islower() True >>> print 'Abcd123#'.islower() False str.isupper() This method checks if all the characters of a string are uppercase characters (A-Z). >>> print 'ABCD123#'.isupper() True >>> print 'Abcd123#'.isupper() False Task: You are given a string S. Your task is to find out if the string S contains: alphanumeric characters, alphabetical characters, digits, lowercase and uppercase characters. Input Format: A single line containing a string S. Constraints: 0<len(S)<1000 Output Format: In the first line, print True if S has any alphanumeric characters. Otherwise, print False. In the second line, print True if S has any alphabetical characters. Otherwise, print False. In the third line, print True if S has any digits. Otherwise, print False. In the fourth line, print True if S has any lowercase characters. Otherwise, print False. In the fifth line, print True if S has any uppercase characters. Otherwise, print False.

## Is This a Binary Search Tree?

For the purposes of this challenge, we define a binary tree to be a binary search tree with the following ordering requirements: The data value of every node in a node's left subtree is less than the data value of that node. The data value of every node in a node's right subtree is greater than the data value of that node. Given the root node of a binary tree, can you determine if it's also a

The square-ten tree decomposition of an array is defined as follows: The lowest () level of the square-ten tree consists of single array elements in their natural order. The level (starting from ) of the square-ten tree consists of subsequent array subsegments of length in their natural order. Thus, the level contains subsegments of length , the level contains subsegments of length , the

View Solution →## Balanced Forest

Greg has a tree of nodes containing integer data. He wants to insert a node with some non-zero integer value somewhere into the tree. His goal is to be able to cut two edges and have the values of each of the three new trees sum to the same amount. This is called a balanced forest. Being frugal, the data value he inserts should be minimal. Determine the minimal amount that a new node can have to a

Jenny loves experimenting with trees. Her favorite tree has n nodes connected by n - 1 edges, and each edge is ` unit in length. She wants to cut a subtree (i.e., a connected part of the original tree) of radius r from this tree by performing the following two steps: 1. Choose a node, x , from the tree. 2. Cut a subtree consisting of all nodes which are not further than r units from node x .
