Here are some important topics for a beginner problem solver:

Loops: Learn how to repeat tasks using for, while, and do-while loops.

Conditionals: Understand how to make decisions using if, else if, and else.

Arrays: Practice storing and accessing multiple values in a single variable.

Functions: Learn how to break your code into reusable blocks.

Recursion: Understand how a function can call itself to solve a problem.

Sorting: Practice ordering numbers or strings using algorithms like bubble sort or insertion sort.

Searching: Learn how to find an item in a list, such as with linear search or binary search.

String manipulation: Practice working with text, including reversing or finding parts of a string.

Mathematics: Practice basic number problems like finding the greatest common divisor (GCD) or prime numbers.

Debugging: Learn how to find and fix errors in your code.

These are fundamental for building a strong problem-solving foundation.
