A bubble sort algorithm is used to sort a telemetry dataset of temperatures (measured in tenths of a degree Celsius) into ascending order.
The initial unsorted list of six readings is:
| 240 | 180 | 310 | 120 | 450 | 150 |
State the number of passes that will be made to fully sort this list.
159 exam-style questions on Edexcel GCSE Computer Science Algorithms, covering Constructs for solving problems, Variables, constants and data structures, Arithmetic, relational and logical operators, Tracing algorithm output with trace tables, Types of error and correcting logic errors, Standard algorithms (sorts and searches), and Evaluating algorithm fitness and efficiency. Each one has a worked solution and a mark scheme showing where the marks go.
