A Linked List is a linear data structure in which each node has two blocks such that one block contains the value or data of the node and the other block contains the address of the next field.Let us assume that we have a linked list such that each node ... Read More

Let us suppose we have two strings 'a' and 'b' and a string 'merge'. The task is to fill the string 'merge' with the characters from 'a' and 'b' in such a way that, If the string 'a' is non-empty, then remove the first character from the string 'a' and ... Read More

Let us suppose we have three numbers. The task is to count the total number of optimal steps to make all these numbers '0'.For ExampleInput-1:a = 4 b = 4c = 6Output:7Explanation: Total number of optimal steps to make all the numbers '0' is, (4, 4, 6)Removing '1' from 1st and ... Read More

Let us suppose we have three integers 'a' and 'b' and 'limit'. The task is to print the numbers in the range [a, limit]. List of these numbers is said to be powerful integers and represented as, a^i + b^j such that i >= 0 and j >= 0For ExampleInput-1:a ... Read More

A string is said to be a palindromic string if it remains the same after reversing it.In this particular problem, we've given two strings 'a' and 'b' of the same length. If they are split with some indexes, then the task is to check whether the sum of the strings ... Read More

Let us suppose we have a binary tree and the task is to check whether it constructs a symmetry of itself or not. A Symmetric Binary tree constructs the mirror image of itself.For ExampleInput-1:           Output:TrueExplanation:Since the given binary tree constructs the mirror image of itself, the output ... Read More

In a binary tree, each node contains two children, i.e left child and right child. Let us suppose we have a binary tree and we need to check if the tree is balanced or not. A Binary tree is said to be balanced if the difference of height of left ... Read More
