Bricks Falling When Hit in C++
Suppose we have a grid of binary values (0s and 1s) the 1s in a cell represent the bricks. A brick will not drop when that satisfies these conditions −Either brick is directly connected to the top of the gridor at least one of its adjacent (top, bottom, left, right) bricks will not drop.We will do some erasures sequentially. In each case we want to do the erasure at the location (i, j), the brick (if that is present) on that location will disappear, and then some other bricks may drop because of that erasure. We have to find the ...
Read MoreReverse Subarray To Maximize Array Value in C++
Suppose we have one integer array called nums. The value of this array is defined as the sum of |nums[i]-nums[i+1]| for all i in range 0 to n - 1. Where n is the size of the array. We can select any subarray of the given array and reverse it. We can perform this operation only once. Then we have to find the maximum possible value of the final array.So, if the input is like [1, 5, 4, 2, 3], then the output will be 10.To solve this, we will follow these steps −ret := 0, extra := 0n := ...
Read MoreMaximum Subarray Sum Excluding Certain Elements in C++
In this tutorial, we will be discussing a program to find maximum Subarray Sum Excluding Certain Elements.For this we will be provided with two arrays of size M and N. Our task is to find a sub-array in the first array such that no element inside the subarray is present inside the second array and the elements of subarray sum up to be maximum.Example#include using namespace std; //checking if element is present in second array bool isPresent(int B[], int m, int x) { for (int i = 0; i < m; i++) if (B[i] == x) ...
Read MoreC program to Replace a word in a text by another given word
In this program, we have given three strings txt, oldword, newword. Our task is to create a C program to replace a word in a text by another given word.The program will search for all the occurrences of the oldword in the text and replace it with newword.Let’s take an example to understand the problem −Inputtext = “I am learning programming” oldword = “learning” newword = “practicing”Output“I am practicing programming”To solve this problem, we will first find the number of occurrence of the oldword in the string and then create a new string which will store the text with replaced ...
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 ...
Read MoreSort the words in lexicographical order in C#
Firstly, set a string array −string[] arr = new string[] { "Indian", "Moroccon", "American", };To sort the words in lexicographical order −var sort = from a in arr orderby a select a;Exampleusing System; using System.Linq; class Program { static void Main() { string[] arr = new string[] { "Indian", "Moroccon", "American", }; var sort = from a in arr orderby a select a; foreach(string res in sort) { Console.WriteLine(res); } } }outputAmerican Indian Moroccon
Read MorePHP abs() Function
Definition and UsageThe abs() function is an in-built function in PHP iterpreter. This function accepts any number as argument and returns a positive value, disregarding its sign. Absolute value of any number is always positive.This function always returns positive number.Syntaxabs( mixed $num)ParametersSr.NoParameter & Description1numThis parameter stores a value whose absolute value is to be obtained.Return ValuesPHP abs() function returns absolute value of num. If data type of num is float, return type is also float.For integer parameter, return type is integer.PHP VersionThis function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.ExampleOutputThis will produce the following ...
Read MorePHP acosh() Function
Definition and UsageThe acosh() function returns the inverse hyperbolic cosine ratio of given angle in of given parameter. In other words, the return value of asinh() is hyperbolic sine of given parameter. A hyperbolic inverse hyperbolic cosine function is defined as −.acosh(x) = log(x+sqrt(pow(x, 2)-1))This function returns a float value.Syntaxacosh ( float $arg ) : floatParametersSr.NoParameter & Description1argA floating point value whose inverse hyperbolic cosine is to be calculatedReturn ValuesPHP acosh() function returns inverse hyperbolic cosine ratio of given parameter.PHP VersionThis function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.ExampleFollowing example calculates acosh(pi/2) and returns ...

Definition and UsageThe asinh() function calculates inverse of hyperbolic sine of given parameter. In other words, the return value of asinh() is hyperbolic sine of given parameter. A inverse hyperbolic sine function is defined asasinh(x) = log(x+sqrt(pow(x,2)+1))This function returns a float value.Syntaxasinh( float $arg ) : floatParametersSr.NoParameter & Description1argA floating point value whose inverse hyperbolic sine is to be calculatedReturn ValuesPHP asinh() function returns inverse hyperbolic sine ratio of given parameter.PHP VersionThis function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.ExampleOutputThis will produce following result −asinh(3.1415926535898) = 1.8622957433108
Read MorePHP bindec() Function
Definition and UsageThe bindec() function returns decinmal equivalent of a binary number represented as a string argument. Binary number inside string is interpreted as unigned integer.This function returns a decimal integer. However, it may return float for size reasons.Syntaxbindec ( string $binary_string ) : numberParametersSr.NoParameter & Description1binary_stringA string containing binary number representation. Invalid characters (other than 1 and 0) are ignored.Return ValuesPHP bindec() function returns decimal equivalent of given binary number inside string.PHP VersionThis function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.Example
