Scala Programming: Check whether two strings of length 3 and 4 appear in same number of times in a given string
Scala Programming String Exercise-38 with Solution
Write a Java program to check whether two strings of length 3 and 4 appear in same number of times in a given string.
Sample Solution:
Scala Code:
object Scala_String {
def test(stng: String, str1: String, str2: String): Boolean = {
val l = stng.length;
var red = 0;
var blue = 0;
for (i <- 0 to l-3)
{
var tmp = stng.substring(i, i+3);
if (tmp.compareTo(str2) == 0)
red=red+1;
}
for (i <- 0 to l-4)
{
var tmp = stng.substring(i, i+4);
if (tmp.compareTo(str1) == 0)
blue=blue+1;
}
if (red == blue)
return true;
else
return false;
}
def main(args: Array[String]): Unit = {
var strr = "redcapmanwithbluecar";
val str1 ="blue";
val str2 ="red";
println("The original string is: "+strr);
println("Searched strings are: "+str1+","+str2);
println("The appearance of red and blue are same: "+test(strr, str1, str2));
strr = "redcapmanwithbluecarblue";
println("The original string is: "+strr);
println("Searched strings are: "+str1+","+str2);
println("The appearance of red and blue are same: "+test(strr, str1, str2));
}
}
Sample Output:
The original string is: redcapmanwithbluecar Searched strings are: blue,red The appearance of red and blue are same: true The original string is: redcapmanwithbluecarblue Searched strings are: blue,red The appearance of red and blue are same: false
