C# Program to convert Digits to Words
Firstly, declare the words from 0 to 9 −// words for every digits from 0 to 9 string[] digits_words = { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" };The following are the digits to be converted to words −// number to be converted into words val = 4677; Console.WriteLine("Number: " + val);Use the loop to check for every digit in the given number and convert into words −do { next = val % 10; a[num_digits] = next; num_digits++; val = val / 10; } while(val > 0);ExampleYou can try to ...
Read MoreC# Program to Convert Decimal to Binary\\n
Let’ s say you have set the decimal to be −decVal = 34; Console.WriteLine("Decimal: {0}", decVal);Use the ToString() method for the values you get as a binary number for the decimal value −while (decVal >= 1) { val = decVal / 2; a += (decVal % 2).ToString(); decVal = val; }Now set a new empty variable to display the binary number using a loop −string binValue = "";ExampleYou can try to run the following code to convert decimal to binary in C#.using System; using System.Collections.Generic; using System.Text; namespace Demo { class MyApplication { ...
Read MoreInterval List Intersections in C++
Suppose we have two lists of closed intervals, here each list of intervals is pairwise disjoint and in sorted order. We have ti find the intersection of these two interval lists.We know that the closed interval [a, b] is denoted as a A[i][1] or A[i][1] B[j][1] or B[j][1] B[j][1]: j+=1 else: i+=1 return result def intersect(self,a,b): if a[0]=b[0]: return True if b[0]=a[0]: return True return False ob = Solution() print(ob.intervalIntersection([[0,2],[5,10],[13,23],[24,25]],[[1,5],[8,12],[15,24],[25,27]]))Input[[0,2],[5,10],[13,23],[24,25]] [[1,5],[8,12],[15,24],[25,27]]Output[[1, 2], [5, 5], [8, 10], [15, 23], [24, 24], [25, 25]]
Read MoreFind elements of an array which are divisible by N using STL in C++
Given with an array and the task is to find the number which are divisible by N using standard template library in C++.To solve this problem we are using the function count_if() present in C++ standard template library.What is a count_if() function?Syntaxcount_if(LowerBound, UpperBound, function)Description − This function returns the number of elements in an array that satisfies the given condition. It takes three parameters.Lower Bound − It points to the first element of an array or any other sequence.Upper Bound − It points to the last element of an array or any other sequence.Function − It returns the Boolean value ...
Read MoreMaximum Nesting Depth of Two Valid Parentheses Strings in Python
Suppose we have a string, that string is a valid parentheses string (denoted VPS) if and only if it consists of "(" and ")" characters only, and it satisfies these properties −It is the empty string, orIt can be written as AB, where A and B are VPS's, orIt can be written as (A), where A is a VPS.We can also define the nesting depth depth(S) of any VPS S like below −depth("") = 0depth(A + B) = max of depth(A), depth(B), where A and B are VPS'sdepth("(" + A + ")") = 1 + depth(A), where A is a ...
Read MoreInfinity or Exception in C# when divide by 0?
Divide by zero is the System.DivideByZeroException, which is a class that handles errors generated from dividing a dividend with zero.Let us see an example.Exampleresult = num1 / num2;Above, if num2 is set to 0, then the DivideByZeroException is caught since we have handled exception.
Read MoreNumber of Closed Islands in C++
Suppose we have a 2D grid consists of 0s (as land) and 1s (as water). An island is a maximal 4- directionally connected group of 0s. A closed island is an island totally surrounded by 1s. We have to find the number of closed islands. So if the grid is like1111111010000110101011101000010111111110So the output will be 2. There are two islands, that are completely surrounded by water.To solve this, we will follow these steps −Define a variable flagDefine a method called dfs, this will take the grid, i, j, n and mif i and j are not inside the range of ...
Read MoreRepresent Int64 as a Hexadecimal String in C#
To represent Int64 as a Binary string in C#, use the ToString() method and set the base as the ToString() method’s second parameter i.e.16 for Hexadecimal.Int64 represents a 64-bit signed integer.Firstly, set an Int64 variable.long val = 947645;Now, convert it to a hex string by including 16 as the second parameter.Convert.ToString(val, 16)Exampleusing System; class Demo { static void Main() { long val = 947645; Console.WriteLine("Long: "+val); Console.Write("Hex String: "+Convert.ToString(val, 16)); } }OutputLong: 947645 Hex String: e75bd
Read MoreWhat is the difference between a class and an object in C#?
When you define a class, you define a blueprint for a data type.Objects are instances of a class. The methods and variables that constitute a class are called members of the class.To access the class members, you use the dot (.) operator after the object name. The dot operator links the name of an object with the name of a member for example, Box Box1 = new Box();Above you can see Box1 is our object. We will use it to access the members −Box1.height = 7.0;You can also use it to call member functions −Box1.getVolume();The following is an example showing ...
Read MoreWrite a Program to Find the Maximum Depth or Height of a Tree in C++
In this problem, we are given a binary tree. Our task is to write a program to find the maximum depth or height of the given tree.Let’s take an example to understand the problem, The height of the tree is 3.To find the maximum height of a tree, we will check the heights of its left and right subtree and add one to the maximum of both. This is a recursive process that will continue this the last node is of the tree is found and one is added progressively to find the height of the sub-trees.Above example solved using ...
