Algorithmic Challenges in Kotlin
Master algorithms in Kotlin with real tests, instant hints, and pro-grade support in an IDE tailored for learning.
About this course
Solve problems like an engineer, one Kotlin algorithm at a time, using IntelliJ IDEA with smart support like hints, test runners, autocompletion, and a built-in debugger.
You’ll tackle real coding challenges using proven techniques: brute force, binary search, divide and conquer, greedy algorithms, and dynamic programming.
Each task starts as a failing unit test. Your goal? Write Kotlin that passes—fast, correct, and clean.
Your result: not just recognizing algorithms, but knowing when and how to apply them. You’ll debug faster, write smarter, and solve harder. And you’ll prove you can handle the challenges that actually get you hired.
