Giving instructions to a computer Thinking like a computer - in binary Using a set of techniques and approaches to help to solve problems None of the above Which of the following is NOT an example of computational thinking? Accidentally completing a video game level Planning how to beat your enemies in a video game level None of the above Planning what to collect and where to exit to complete a video game level Which computational thinking technique involves breaking a problem down into smaller parts? Algorithm Generalisation Abstraction Decomposition There are 3 pillars of computational thinking except Abstraction Decomposition Coding Generalisation Suppose we have the following sorted list of 10 items. 3,5,6,8,11,12,14,15,17,28 Which is the correct sequence of comparisons when finding the 8 using a binary search? (Hint: in case of even list go with the right element) 11,5,6,8 3,5,6,8 12,6,8 11,6,5,8 A list contains the names: George, Jane, Miranda, Ahmed, Sophie, Bernie, Keith. They are sorted using Insertion sort. What is the first name to be moved? Miranda Sophie Jane Ahmed Using the same list as before: George, Jane, Miranda, Ahmed, Sophie, Bernie, Keith. How many names have to be moved altogether before the list is sorted using Insertion sort? 5 3 6 1 "Performing a series of different set-up operations when the computer is switched on" Is an example of which of the following? Selection Variables Iteration Sequence "Deciding whether to use the DayTimeRate or EveningRate functions to calculate a customers fare" ,Is an example of which of the following. Sequence Sorting Iteration Selection Which sorting algorithm may make multiple swaps per pass? Insertion Sort Bubble Sort Selection Sort Merge Sort Which sorting algorithm shifts elements instead of swapping elements if needed in each pass Merge Sort Selection Sort Insertion Sort Bubble Sort The following lists represent 3 passes of a sorting algorithm. Which algorithm is being used to sort the list? 4 5 9 6 2 7 4 5 6 2 7 9 4 5 2 6 7 9 InsertionSort Bubble Sort Merge Sort Bogo Sort The following lists represent 3 passes of a sorting algorithm. Which algorithm is being used to sort the list? 4 8 6 2 5 7 4 8 6 2 5 7 4 6 8 2 5 7 Bubble Sort Insertion Sort Merge Sort We are sorting the following list in ascending order: 1 4 2 9 3 8 5 What does the list look like after one pass of the bubble sort algorithm 1 2 4 3 8 5 9 1 4 2 5 3 8 9 4 2 9 3 8 5 1 We are sorting the following list in ascending order: 1 4 2 9 3 8 5What does the list look like after one pass of the Insertionsort algorithm 4 2 9 3 8 5 1 4 1 2 9 3 8 5 1 4 2 9 3 8 5 C A B D A B C D A B C D A B C D A B C D A B C D A B C D A B C D A B C D B C D A Sort the following list using Bubble sort and write the position of numbers at the end of each pass.5 1 4 2 8 (Note: use single space to seperate numbers) pass-1 pass-2 Sort the following list using insertion sort? 4 3 2 10 12 1 5 6 (please list all steps) Sort the following List using Merge Sort 38 27 43 3 9 82 10 |
