Implementing MinStack In JavaScript With O(1) GetMin()

29d

Implementing MinStack in JavaScript: Use an auxiliary stack (minStack) to store the minimum element at each step, enabling O(1) time complexity for getMin(). Push and pop operations remain O(1).

Implementing MinStack in JavaScript

  
  
  Problem Statement

Design a stack that supports push, pop, top, and retrieving the minimum element in constant time.

  
  
  Requirements:


push(val): Pushes the element val onto the stack.
pop(): Removes the element on top of the stack.
top(): Retrieves the top element.
getMin(): Retrieves the minimum element in O(1) time.

  
  
  Optimized Approach (Using an Auxiliary Stack)

An auxiliary stack is an additional stack used alongside the main stack to store extra information that helps optimize certain operations.
In the case of MinStack, we use...
