Question

Suppose s is a string, and that the call s.indexOf("an") returns 3. Which of the following could be the value of s?

a) advance
b) meaning
c) breathing
d) banana
e) anachronism

Answer 1

The value of s could be d) 'breathing'.

Step-by-step explanation:

The given question is related to computer science.

When the indexOf() method is called on a string, it returns the index of the first occurrence of a specified substring within the string. In this case, if s.indexOf('an') returns 3, it means that the substring 'an' is found at index 3 within the string s. Let's analyze the given options:

• a) advance - The substring 'an' is not found at index 3, so this cannot be the value of s.
• b) meaning - The substring 'an' is not found at index 3, so this cannot be the value of s.
• c) breathing - The substring 'an' is found at index 3, so s could be 'breathing'.
• d) banana - The substring 'an' is not found at index 3, so this cannot be the value of s.
• e) anachronism - The substring 'an' is not found at index 3, so this cannot be the value of s.

Therefore, the value of s could be 'breathing'.
