Scala Programming: Read a string, if the first or last characters are same return the string without those characters otherwise return the string unchanged

Scala Programming String Exercise-25 with Solution

Write a Scala program to read a given string and if the first or last characters are same return the string without those characters otherwise return the string unchanged.

Sample Solution:

Scala Code:

object Scala_String {

  def test(str1: String, c: Char): String = {
    var temp_str = str1
    if (temp_str.length == 0)
      return temp_str;
    if (temp_str.length == 1) {
      if (temp_str.charAt(0) == c)
        return "";
      else
        return temp_str;
    }
    if (str1.charAt(0) == c)
      temp_str = temp_str.substring(1, temp_str.length);
    if (str1.charAt(str1.length - 1) == c)
      temp_str = temp_str.substring(0, temp_str.length - 1);
    return temp_str;
  }

  def main(args: Array[String]): Unit = {
    var str1 = "testcricket";
    var c = 't'
    println("The given strings is: " + str1);
    println("The new string is: " + test(str1, c));

    str1 = "testcricket";
    c = 'e'
    println("The given strings is: " + str1);
    println("The new string is: " + test(str1, c));
  }
}

Sample Output:

The given strings is: testcricket
The new string is: estcricke
The given strings is: testcricket
The new string is: testcricket

Previous: Write a Scala program to check whether the first two characters present at the end of a given string.
Next: Write a Scala program to read a string and return the string without the first two characters. Keep the first char if it is 'g' and keep the second char if it is 'h'.
