SKILL BENCHMARK

Java Data Structures Literacy (Beginner Level)

  • 15m
  • 15 questions
The Java Data Structures Literacy (Beginner Level) benchmark assesses your knowledge of the importance of data structures and algorithms in writing efficient and correct code and the differences between abstract data types and data structures. You will be evaluated on your skills in using complexity to measure the performance of your code based on running time, space, network usage, and other resources and analyzing different methods to determine their running time using big O notation. A learner who scores high on this benchmark demonstrates that they have the skills to recognize the importance of data structures and algorithms in writing fast and efficient code, analyzing code, and expressing time complexity with big O notation.
