Hey coder!! Congrats on making it this far. Acciojob's DSA test series is aimed at giving the participants an idea of how the coding rounds of various companies are designed. These questions not only test your knowledge of Data Structures and Algorithm, but also test your analytical skills and quick thinking. The part 4 of this series aims at testing your knwledge of concepts like sorting, sliding window and hashing. The level of the competition is on the hard side and the expected time taken to solve it is 90 minutes.
