Question

ArrayListSearch(numList, 78) executes. How many elements in the list will be compared with 78 ? What is returned? Next, ArrayListRemoveAt(numList, 0) executes. ArrayListSearch(numList, 78) executes again. How many elements in the list will be compared with 78 ? What is returned? ArrayListSearch(numList, 27) executes. How many elements in the list will be compared with 27 ? What is returned?

Answer 1

The ArrayListSearch function compares elements in a list with a given value and returns the index if found, otherwise -1.

Step-by-step explanation:

In the first execution of ArrayListSearch(numList, 78), all the elements in the list will be compared with 78. If the element is found, its index is returned, otherwise -1 is returned. In the second execution of ArrayListSearch(numList, 78) after removing the first element with ArrayListRemoveAt(numList, 0), one less element will be compared with 78. If the element is found, its new index is returned, otherwise -1 is returned.

When ArrayListSearch(numList, 27) is executed, all the remaining elements in the list will be compared with 27. If the element is found, its index is returned, otherwise -1 is returned.
