- 155. Min Stack
- 242. Valid Anagram
- Asked to create a Linked List and a method to insert a node at the end of the Linked List.
Expectations: To solve the problems with working code & all test case to be passed. No discussion on TC and SC.
Interview Questions (3)
Min Stack
Design a stack that supports push, pop, top, and retrieving the minimum element in constant time. Implement the following operations:
push(x): Push element x onto the stack.pop(): Remove the element on top of the stack.top(): Get the top element.getMin(): Retrieve the minimum element in the stack. All operations must run in O(1) time.
Valid Anagram
Given two strings s and t, return true if t is an anagram of s, and false otherwise.
An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.
Linked List Insert at End
Implement a singly linked list and provide a method to insert a node at the end of the list. The method should handle an empty list as well as a non‑empty list, ensuring the new node becomes the tail of the list.
