Scala Programming: Count and print all the duplicates in the input string
Scala Programming String Exercise-17 with Solution
Write a Scala program to count and print all the duplicates in the input string.
Sample Solution:
Scala Code:
object Scala_String {
def showDuplicates(str1: String): Unit = {
val MAX_CHARS = 256;
val ctr = new Array[Int](MAX_CHARS);
for (i <- 0 to str1.length - 1)
ctr(str1.charAt(i)) = ctr(str1.charAt(i)) + 1;
for (i <- 0 to MAX_CHARS - 1)
if (ctr(i) > 1)
printf("%c appears %d times\n", i, ctr(i));
}
def main(args: Array[String]): Unit = {
val str1 ="w3resource";
println("The given string is: " + str1);
println("The duplicate characters and counts are: ");
showDuplicates(str1);
val str2 ="The Scala Programming Language";
println("The given string is: " + str2);
println("The duplicate characters and counts are: ");
showDuplicates(str2);
}
}
Sample Output:
The given string is: w3resource The duplicate characters and counts are: e appears 2 times r appears 2 times The given string is: The Scala Programming Language The duplicate characters and counts are: appears 3 times a appears 5 times e appears 2 times g appears 4 times m appears 2 times n appears 2 times r appears 2 times
