In the given problem, we have to update the bit of the given index of a number. To update the number, we can use Bit Manipulation operation on a given number. For example, Input-1 −N= 25 bit= 1 position= 2Output −29Explanation − Since the given input 25 can be written ... Read More

static_assert is a function which is useful for programmers to print the error in the screen after compiling the program without messing up with the output too much.Earlier in C++11 and C++14, static_assert had different functionality which means we have to write our own message while defining the static_assert. However, ... Read More

In the given array of sorted integers, the task is to print the squares of every array element and print the array in sorted order. For example, Input-1 −arr[ ] = { -3, -1, 0, 1, 4, 6 };Output −{0, 1, 1, 9, 16, 36}Explanation − The squares of each ... Read More

Given an array of 0, 1 and 2 sort the element in an order such that all the zeros come first before 1 and all the 2’s in the end. We have to sort all the elements of the array in-place.We can solve this problem using DNF (Dutch National Flag) ... Read More

Given an array of 0, 1, and 2, sort the elements in an order such that all the zeros come first before 1 and all the 2’s in the end. We have to sort all the elements of the array in-place.We can solve this problem using DNF (Dutch National Flag) ... Read More

Lambda Function − Lambda are functions is an inline function that doesn’t require any implementation outside the scope of the main program.Lambda Functions can also be used as a value by the variable to store. Lambda can be referred to as an object that can be called by the function ... Read More

Given a singly linked list, the task is to search a particular element in the linked list. If the element is found, then print “present” otherwise “Not present”. For example, Input-1 −1→ 2→ 3→ 4→ 5→ 6Searching for ‘7’Output −Not PresentExplanation − In the given singly linked list the element ... Read More

Let’s suppose we have given a square matrix of N×N. The task is to rotate the matrix counterclockwise. For example, Input-1 −N = 3 matrix[ ][ ] = [    [1 2 3],    [4 5 6],    [7 8 9] ]Output −3 6 9 2 5 8 1 4 ... Read More

Given a string, the task is to reverse all the vowels present in the given string. For example, Input-1 −a = “tutor”Output −toturExplanation − Reversing the string “tutor” will generate the output as “totur.Input-2 −a = “mathematics”Output −mithametacsExplanation − Reversing the string “mathematics” will generate the output as “mithametacs”.Approach to ...
