Day 21: LeetCode Easy

Tasks/Activities:

Activity 1: Two Sum

• Task 1: Solve the "Two Sum" problem on LeetCode.
  • Write a function that takes an array of numbers and a target number, and returns the indices of the two numbers that add up to the target.
  • Log the indices for a few test cases.

Activity 2: Reverse Integer

• Task 2: Solve the "Reverse Integer" problem on LeetCode.
  • Write a function that takes an integer and returns it with its digits reversed.
  • Handle edge cases like negative numbers and numbers ending in zero.
  • Log the reversed integers for a few test cases.

Activity 3: Palindrome Number

• Task 3: Solve the "Palindrome Number" problem on LeetCode.
  • Write a function that takes an integer and returns true if it is a palindrome, and false otherwise.
  • Log the result for a few test cases, including edge cases like negative numbers.

Activity 4: Merge Two Sorted Lists

• Task 4: Solve the "Merge Two Sorted Lists" problem on LeetCode.
  • Write a function that takes two sorted linked lists and returns a new sorted list by merging them.
  • Create a few test cases with linked lists and log the merged list.

Activity 5: Valid Parentheses

• Task 5: Solve the "Valid Parentheses" problem on LeetCode.
  • Write a function that takes a string containing just the characters '(', ')', '{', '}', '[' and ']', and determines if the input string is valid.
  • A string is valid if open brackets are closed in the correct order.
  • Log the result for a few test cases.
