Which data structure is best suited for implementing a function that reverses a string?
Step 1: Understand what reversing a string means. It means changing the order of characters so that the last character becomes the first, the second last becomes the second, and so on.
Step 2: Learn about data structures. A data structure is a way to organize and store data in a computer.
Step 3: Identify the stack data structure. A stack is a collection of elements that follows the Last In First Out (LIFO) principle.
Step 4: Understand LIFO. This means that the last element added to the stack is the first one to be removed.
Step 5: Think about how to use a stack to reverse a string. You can push each character of the string onto the stack one by one.
Step 6: Once all characters are pushed onto the stack, pop them off one by one. The first character popped will be the last character of the original string, effectively reversing it.
Step 7: Conclude that using a stack is efficient for reversing a string because it allows you to easily access the last character added.
