When it is required to find the largest value in a tree using in order traversal, a binary tree class is created with methods to set the root element, perform in order traversal using recursion and so on.An instance of the class is created, and it can be used to ... Read More

When it is required to calculate the number of words and characters present in a string, Below is the demonstration of the sameExample Live Demomy_string = "Hi there, how are you Will ? " print("The string is :") print(my_string) my_chars=0 my_words=1 for i in my_string:    my_chars=my_chars+1    if(i==' '):   ... Read More

When it is required to remove characters from odd indices of a string, a method is defined that takes the string as parameter.Below is the demonstration of the same −Example Live Demodef remove_odd_index_characters(my_str):    new_string = ""    i = 0    while i < len(my_str):       if (i ... Read More

When it is required to perform depth first search on a tree using recursion, a class is defined, and methods are defined on it that help perform breadth first search.Below is a demonstration for the same −Example Live Democlass BinaryTree_struct:    def __init__(self, key=None):       self.key = key   ... Read More

When it is required to sort a binary search tree, a class is created, and methods are defined inside it that perform operations like inserting an element, and performing inorder traversal.Below is a demonstration of the same −Exampleclass BinSearchTreeNode:    def __init__(self, key):       self.key = key   ...

When it is required to concatenate a matrix vertically, the list comprehension can be used.Below is a demonstration of the same −Example Live Demofrom itertools import zip_longest my_list = [["Hi", "Rob"], ["how", "are"], ["you"]] print("The list is : ") print(my_list) my_result = ["".join(elem) for elem in zip_longest(*my_list, fillvalue ... Read More

When it is required to get the ‘n’th column of a matrix, the ‘any’ method can be used.Below is a demonstration of the same −Example Live Demomy_list = [[34, 67, 89], [16, 27, 86], [48, 30, 0]] print("The list is : ") print(my_list) N = 1 print("The value of ... Read More

When it is required to create a matrix of dimension n * n, a list comprehension is used.Below is a demonstration of the same −Example Live DemoN = 4 print("The value of N is ") print(N) my_result = [list(range(1 + N * i, 1 + N * (i + 1))) ... Read More

When it is required to read the height in ‘cm’ and convert it into ‘feet’ and ‘inches’, the ‘round’ method can be used.Below is a demonstration of the same −Example Live Demoin_cm=int(input("Enter the height in centimeters...")) in_inches=0.394*in_cm in_feet=0.0328*in_cm print("The length in inches is ") print(round(in_inches, 2)) print("The length in feet is") ...
