Peek(): This operation is used to get the value of the element from the front of the queue. Working of queue: We can implement queue by using two pointers i.e. FRONT and REAR. FRONT is used to track the first element of the queue. REAR is used to track the last element of the ...

check if the queue is empty return the value pointed by FRONT increase the FRONT index by 1 for the last element, reset the values of FRONT and REAR to -1 Enqueue and Dequeue Operations Queue Implementations in Python, Java, C, and C++ We usually use arrays to implement queues in Java...
Working of Stack Data Structure Stack Implementations in Python, Java, C, and C++ The most common stack implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Stack implementation in python # Creating a stack def create_stack(): stack = [] return...
In C++, strings can be represented using three ways. Using Two-dimensional Character Arrays:This representation uses the two-dimensional arrays where each element is the intersection of a row and column number and represents a string Using String Keyword:We can also use the string keyword of C++...
