Data Structures and Algorithms Basics

For engineering students preparing for product-company and IT-services coding rounds and technical interviews. Covers Big-O analysis, arrays, linked lists, stacks and queues, trees, graphs, sorting and searching, and hashing. A pass means you know the core structures, their costs and which to pick for a given problem.

How the test runs

  • The timer runs on the server

    It starts when you press Start and keeps running if you reload, switch tabs or lose connection. Under a minute left, the clock turns red.

  • Answers save as you go

    Every change is saved within seconds and again every ten seconds. Leave and come back while time remains and the test resumes where you were.

  • Auto-submit at zero

    When the clock hits zero, whatever you have answered is submitted and scored. Unanswered questions count as wrong; there is no negative marking.

  • One attempt in progress

    You can have one attempt of this test running at a time. Submit it (or let it expire) to start a fresh one with a new timer.

  • Keyboard friendly

    Keys 1 to 4 choose an option, the left and right arrows move between questions, and the palette jumps anywhere. Flag a question to come back to it.

Pseudocode and Output Prediction

For freshers sitting the Infosys, Accenture, Capgemini, Wipro and TCS NQT style pseudocode sections. Every question gives a short language-neutral snippet and asks you to dry-run it: loops, conditionals, arrays, strings, recursion, operator precedence and pass-by-value. A pass means you can trace code on paper accurately and fast enough for a timed online test.
