Question

3 (07.04 mc) consider the code below, which uses ap exam pseudocode. the code segment is intended to extract the string back from the string backyard; however, it does not work correctly. y = substring(\backyard\, 0, 4) which of the following code segments would work correctly? (5 points) y = substring(\backyard\, 0, 3) y = substring(\backyard\, 2, 4) y = substring(\backyard\, 1, 4) y = substring(\backyard\, 1, 3)

Explanation:

Step1: Understand substring function

The substring function usually takes a string, a starting - index (inclusive), and a length.

Step2: Analyze "back" in "backyard"

The word "back" starts at index 1 (counting from 0) and has a length of 4 characters. So Substring("backyard", 1, 4) will extract "back".

Answer:

y = Substring("backyard", 1, 4)
