A balanced expression of parentheses is an expression that contains pairs of all sort of parentheses together in a correct order.this means that for every opening parentheses there is a closing parentheses in proper order of parentheses i.e. { }.let's take a few examples to understand the concept better −Expression − {([][]{})({}[]{})}Output − balancedExplanation − we can see that for every opening parentheses there is a closing parentheses. all the parentheses lying between an opening parentheses and closing parentheses in Pairs.Output − not balanceExplanation − there are some unordered pairs of parentheses which makes the the expression unbalanced.In this problem ...

STATEMENT − Balance pans using given weights that are powers of a number.DESCRIPTION − In this problem we are given a pan based weighing machine. we are given a weight T and some other weights whose values are powers of a number a. We need to balance the pans using the given weights.Now, based on this we have this equation, T + (some power of a) = (some other power of a)Now, we should remember that there is exactly one weight corresponding to a power value.Example, T = 12 : a = 4Using the below values, we can balance the ...

Bakhshali approximation is a method of computing the square root of a number which is not a perfect square. Now, lets brush-related terms to easily understand the concept.Square root of a number x is a number that satisfies the following condition, y2 = x.Perfect Square is a number whose square roots are w. For example 16 is perfect square as its roots are 4 and 4.There are multiple methods defined mathematically to find the square root of a number. In this tutorial, we are going to learn about Bakhshali approximation to find the square root of a number.It is a ... Read More

Backtracking is a technique based on algorithm to solve problem. It uses recursive calling to find the solution by building a solution step by step increasing values with time. It removes the solutions that doesn't give rise to the solution of the problem based on the constraints given to solve the problem.Backtracking algorithm is applied to some specific types of problems, Decision problem used to find a feasible solution of the problem.Optimisation problem used to find the best solution that can be applied.Enumeration problem used to find the set of all feasible solutions of the problem.In backtracking problem, the algorithm ...

The complete binary tree that follows the properties of heap ordering is called binary heap.Based on the ordering of binary heap, it can be of two types −min Heap is the heap in which the value of node is greater than or equal to the value of its parent node. The root node of min heap is smallest.max Heap is the heap in which the value of node is smaller than or equal to the value of its parent node. The root node of max heap is greatest.The values of binary heap is typically represented as an array. The array ... Read More

The Uri.IsBaseOf() method in C# is used to determine whether the current Uri instance is a base of the specified Uri instance.SyntaxFollowing is the syntax −public bool IsBaseOf (Uri uri);Above, the parameter Uri is the specified Uri instance to test.ExampleLet us now see an example to implement the Uri.IsBaseOf() method −using System; public class Demo {    public static void Main(){       Uri newURI1 = new Uri("https://www.tutorialspoint.com/index.htm");       Console.WriteLine("URI = "+newURI1);       Uri newURI2 = new Uri("https://www.tutorialspoint.com/");       Console.WriteLine("URI = "+newURI2);       if(newURI1.Equals(newURI2))          Console.WriteLine("Both the URIs ...
