Remove First and Last Character

StringsFundamentals

Task

Your goal is to write a function that removes the first and last characters of a string. You're given one parameter, the original string.

Important: Your function should handle strings of any length ≥ 2 characters. For strings with exactly 2 characters, return an empty string.

Examples

'eloquent' --> 'loquen'
'country'  --> 'ountr' 
'person'   --> 'erso'
'ab'       --> '' (empty string)
'xyz'      --> 'y'

Requirements

  • The input string will always have at least 2 characters
  • For strings with exactly 2 characters, return an empty string
  • For strings with 3 or more characters, remove the first and last character
  • The function should handle strings containing letters, numbers, and special characters

Test Cases

Your solution will be tested against:

  • Basic functionality with common words
  • Edge cases with 2-character and 3-character strings
  • Strings containing numbers and special characters
  • Random test cases of varying lengths
