Here are some classic algorithm questions that continue to be relevant for beginners in 2025:

1. Two Sum

Problem Description: Given an array of integers and a target sum, find two numbers in the array that add up to the target sum.

Why It’s Beginner-Friendly:

  • Reinforces basic array manipulation and understanding of hash maps.

Solution Approach:

  • Use a hash map to store each number’s compliment relative to the target sum.

2. Reverse a String

Problem Description: Write a function that reverses a given string.

Why It’s Beginner-Friendly:

  • Encourages practice with string manipulation and understanding of stacks.

Solution Approach:

  • Iterate over the string while constructing the reverse, or use built-in Python functionality.

3. Fibonacci Sequence

Problem Description: Generate the Fibonacci sequence up to a given number.

Why It’s Beginner-Friendly:

  • Demonstrates recursive solutions and iterative approaches.

Solution Approach:

  • Implement both iterative and recursive methods to understand both perspectives.

4. Merge Two Sorted Lists

Problem Description: Merge two sorted linked lists into one sorted list.

Why It’s Beginner-Friendly:

  • Good practice for working with linked lists and understanding pointers.

Solution Approach:

  • Use a two-pointer technique to merge nodes in order.

5. Valid Parentheses

Problem Description: Determine if a string of parentheses is valid.

Why It’s Beginner-Friendly:

  • Strengthens understanding of stacks and nested structures.

Solution Approach:

  • Use a stack to track opening parentheses and ensure they are properly closed.
