In this problem, we need to increase each character of multiple prefixes of size given in the array. The naïve approach to solving the problem is to take each prefix of the size given in the array and increment each character of the prefix by 1. The best approach is to create the prefix array using the given array and update each string character in the single iteration. Problem statement − We have given a string alpha of length N. Also, we have given a prefixes array containing the positive integer. The prefixes[i] represent that take prefix of length prefixes[i] ... Read More
There are two types of variables: global variables and local variables. The scope of global variables is the entire program whereas the scope of local variable is limited to the function where it is defined.Example def func(): x = "Python" s = "test" print(x) print(s) s = "Tutorialspoint" print(s) func() print(x) OutputIn above program- x is a local variable whereas s is a global variable, we can access the local variable only within the function it is defined (func() above) and ...

A stack is an abstract data structure that contains a collection of elements. Stack implements the LIFO mechanism i.e. the element that is pushed at the end is popped out first. Some of the principle operations in the stack are −Push - This adds a data value to the top of the stack.Pop - This removes the data value on top of the stackPeek - This returns the top data value of the stackA program that implements a stack using array is given as follows.Example#include using namespace std; int stack[100], n=100, top=-1; void push(int val) { if(top>=n-1) ...
