COSC 102 Exam 2 Questions and
Answers Graded A+
Which sorting algorithm divides the array into sorted and unsorted sublists? -
Correct answer-Selection
I am running the insertion sort algorithm, and currently at element 10 (the third
element in the list).
This is the state of my array: {15, 20, 10, 5, 35, 25}.
What step do I take next? - Correct answer-10 will be placed before 15, and 15 and
20 will be shifted to the right by one index
(T/F) With selection sort, we find the final position for an element with each step. -
Correct answer-True
Give the result of the following operation in hexadecimal. Both capital and
lowercase letters are accepted if needed. 0x4A & 0xB7 = 0x - Correct answer-02, 2
Convert 0b0001_1010 to decimal. - Correct answer-26
