Given an algebraic string like p-(q-r)-s, we need to remove the brackets and convert this string to a string with the same mathematical result. So the string p-(q-r)-s is converted to p-q+r-s, giving us the same mathematical result. To achieve this, we can use a stack and keep track of ... Read More

The parallel array is also called the structure array.Definition − A parallel array can be defined as multiple arrays in which the ith elements are closely related, and together, they constitute an entity. An array is a fundamental feature in the C++ language. Making parallel arrays helps us in comparing ... Read More

In this tutorial, we need to solve palindrome substring queries of the given string. Solving palindrome substring queries is far more complex than solving regular queries in C++. It requires a far more complex code and logic.In this tutorial, we are provided string str and Q number of substring[L...R] queries, ... Read More
