Suppose We Have Two String Objects and Treat the Characters

question 63

Multiple Choice

Suppose we have two String objects and treat the characters in each string from beginning to end in the following way: With one string, we push each character on a stack. With the other string, we add each character to a queue. After processing both strings, we then pop one character from the stack and remove one character from the queue, and compare the pair of characters to each other. We do this until the stack and the queue are both empty. What does it mean if all the character pairs match?

• A) The strings are the identical.
• B) The strings are different.
• C) One string is the reverse of the other.
• D) We can only conclude the strings are of the same length
