Question

Develop a function called reverse string that accepts a string argument and returns the reverse of that argument. Use iteration to perform the reversal - Do NOT use var-1)

Example: reverse_string("ABC DEF") should return "FED CRA"
Demonstrate its use by printing the result of the example above.

Answer 1

The task is to develop a function called reverse_string which iterates over a string in reverse to construct a new reversed string. An example in Python is provided, showing how the function would appear and be used to obtain the reversed form of "ABC DEF", which should output "FED CBA".

Step-by-step explanation:

The question pertains to writing a function in a programming language that reverses a given string by iterating through it. To accomplish this task, we can create a function called reverse_string which takes a single string argument. The function will use a loop to iterate over the characters of the string in reverse order and append them to a new string.

Here is a potential Python implementation of this function:

def reverse_string(s):
reversed_string = ""
for i in range(len(s) - 1, -1, -1):
reversed_string += s[i]
return reversed_string

You can demonstrate the usage of this function as follows:

print(reverse_string("ABC DEF")) # Output: "FED CBA"

Note that the correct reversed string for "ABC DEF" is "FED CBA", as each character needs to be in the exact reverse order, including spaces.
