How would you like to learn today? Visualize algorithms in real time, explore them step by step through reading, or challenge yourself with a test.
Visualize the algorithm step-by-step with interactive animations. See exactly how the code executes in real time.
Read comprehensive problem explanation, reference links, and explore the code at your own pace.
Drag and arrange the algorithm steps in the correct execution order.
Follow every state change, comparison, and transformation as the execution unfolds in real time, so you understand not just the result, but the journey.
Problem's algorithm is divided into three logical parts. Carefully rearrange each section in the correct order, one by one, to form a complete and valid algorithm.
Green text means the instruction is placed in the correct position.
Red text means the instruction is in the wrong position.
Instructions with the same background color indicate particular blocks start and end.
A tick mark means the instruction is correct and locked.
🔒 Locked steps cannot be moved. Only unlocked steps are draggable.
🔊 Enable sound for swap feedback and completion effects.
