Scala Programming: Read a string and if one or both of the first two characters is equal to specified character return without those characters otherwise return the string unchanged
Scala Programming String Exercise-27 with Solution
Write a Scala program to read a string and if one or both of the first two characters is equal to specified character return without those characters otherwise return the string unchanged.
Sample Solution:
Scala Code:
object Scala_String {
def test(str1: String, c: Char): String = {
var temp = "";
for (i <- 0 to str1.length - 1) {
if (i == 0 && str1.charAt(i) != c)
temp += str1.charAt(i);
else if (i == 1 && str1.charAt(i) != c)
temp += str1.charAt(i);
else if (i > 1)
temp += str1.charAt(i);
}
return temp;
}
def main(args: Array[String]): Unit = {
var str1 ="aacyte";
var c ='a'
println("The given strings is: " + str1 + ", specified character is: " + c);
println("The new string is: " + test(str1, c));
str1 ="bacyte";
c ='a'
println("The given strings is: " + str1 + ", specified character is: " + c);
println("The new string is: " + test(str1, c));
str1 ="bbacyte";
c ='a'
println("The given strings is: " + str1 + ", specified character is: " + c);
println("The new string is: " + test(str1, c));
}
}
Sample Output:
The given strings is: aacyte, specified character is: a The new string is: cyte The given strings is: bacyte, specified character is: a The new string is: bcyte The given strings is: bbacyte, specified character is: a The new string is: bbacyte
