In this problem, we are given two arrays A and B of n elements each. Our task is to create a program to find the maximum possible XOR of every element in an array with another array.We have to compute the maximum XOR for each element of array A with array B i.e. for each element of array A we will select an element in array B which will have the maximum XOR value.Let's take an example to understand the problem −Input −array A = {3, 6 ,11, 9} array B = {8, 2, 4, 1}Output −11 14 15 13Explanation−Let’s ...

Problem statementGiven an Array of non-negative integers. Find out three elements from the array which form a triangle of maximum perimeterExampleIf input array is {5, 1, 3, 5, 7, 4} then maximum perimeter is (7 + 5 + 5) = 17AlgorithmSort the array in non-increasing order. So, the first element will be maximum and the last will be minimumIf the first 3 elements of this sorted array forms a triangle, then it will be the maximum perimeter triangleExample Live Demo#include using namespace std; int getMaxPerimeter(int *arr, int n) {    sort(arr, arr + n, greater());    int maxPerimeter = 0; ...

In this problem, we are given a 2D matrix of size M*N. Our task is to create a program that will find the maximum path sum in the matrix.Here, the maximum path sum in the matrix is defined as the sum of all elements for one row to the last row. The allowed moves for traversing the path are downward move and diagonal move. The start and endpoints can be any element of the first and last row of the matrix respectively.Let's take an example to understand the problemInput −matrix [][] =    3 5 9    1 7 2 ... Read More

Given with an array and the task is to find the number of odd and even elements in an array 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 ...

Isprint() in C++ is inbuilt function in “cctype.h” header file which checks whether the character is printable or not.Isprint returns true for constant cases as Isprint aside from the house character (' '), that returns true.A locale-specific model version of this function (Isprint) exists in cctype header file.-Isprint() function can be used to check any Non-Printing character in a series of sentences.-Isprint() is an Inbuilt function that provides efficient way to handle non printing characters-Isprint() helps to minimize the lines of code for programmer.-Isprint() is in true sense decreases the compilation time of program.Including cctype.h in your program not only ...

Given is the task to show the working of forward_list::emplace_after() and forward_list::emplace_front() functions in c++.A forward_list only keeps linkage with the next element unlike normal list that keeps linkage with the next as well as the preceding elements, which helps iterations in both directions. But forward_list can only iterate in the forward direction.The forward_list::emplace_after() and forward_list::emplace_front() functions are a part of the c++ standard library.The forward_list::emplace_after() function is used to insert a new element inside a list after the element whose position is specified inside the argumentThe forward_list::emplace_front() function is used to insert an element in the beginning of the ...

Given is the task to show the working of forward_list::cbefore_begin() function in C++.A forward_list only keeps linkage with the next element unlike normal list that keeps linkage with the next as well as the preceding elements, which helps iterations in both directions. But forward_list can only iterate in the forward direction.The forward_list::cbefore_begin() function is a part of the C++ standard template library. It is used to obtain the position before the first element of the list. header file should be included to call this function.SyntaxForward_List_Name.cbefore_begin();ParametersThe function does not accept any parameter.Return ValueThe function returns a constant iterator that points at ...

Given is the task to show the working of forward_list::cend functions in C++.A forward_list only keeps linkage with the next element unlike normal list that keeps linkage with the next as well as the preceding elements, which helps iterations in both directions. But forward_list can only iterate in the forward direction.The forward_list::cend() function is a part of the C++ standard template library. It is used to obtain the last element of the list. header file should be included to call this function.SyntaxForward_List_Name.cend();ParametersThe function does not accept any parameter.Return ValueThe function returns a constant iterator that points at the last element ...
