Scala Programming Basic Exercise-5 with Solution
Write a Scala program to check a given integer and return true if it is within 20 of 100 or 300.
Sample Solution:
Scala Code:
object scala_basic {
def test(x:Int) : Boolean =
{
Math.abs(100 - x) <= 20 || Math.abs(300 - x) <= 20
}
def main(args: Array[String]): Unit = {
println("Result: " + test(115));
println("Result: " + test(200));
println("Result: " + test(250));
