Peek algorithm in stack
WebOct 13, 2024 · Peek is an operation to find top value or that returns the value of the topmost component of the stack without removing it from the stack. But, the Peek operation first verifies if the stack is empty, i.e., if TOP = NULL, then a relevant message is printed, else the value is returned. Algorithm for peek operation 1 2 3 4 5 Step 1: IF TOP = NULL WebA Stack is a Linear Data Structure in which Operations are performed in a specific order known as LIFO (Last In First Out) or FILO (First In Last Out). Operations on Stack occur only at one end called as the TOP of the stack. Stack can be implemented using Arrays and LinkedLists. Stack have many applications like:

WebApr 4, 2024 · PEEK Operation Using peek operation topmost element of the stack will be retrieved without deleting it from the stack. PEEK Operation Algorithm Step 1 – Check whether TOP == NULL of Stack. Step 2 – If TOP == NULL then print “Stack is Empty” and terminate the function Step 3 – If TOP != NULL, then display top->data. Step 4 – END 4).
WebPush an element. STEP 1 START. STEP 2 Store the element to push into array. STEP 3 Check if top== (MAXSIZE-1) then stack is full else goto step 4. STEP 4 Increment top as top = top+1. STEP 5 Add element to the position stk [top]=num. STEP 6 STOP. WebA stack can be used to convert a number from one base to another base. Given a number, n, which we want to convert to a base, b, here is the algorithm for performing the conversion: The rightmost digit of n is n % b. Push this digit onto the stack. Replace n with n / b. Repeat steps 1 and 2 until n = 0 and there are no significant digits remaining.
