This solution passes all tests for me:
object Solution {
def main(args: Array[String]) {
var t = scala.io.StdIn.readLine().toInt
for( cas <- 1 to t) {
var line = scala.io.StdIn.readLine()
var a = ""
var b = ""
for( i <- 0 to line.size-1) {
if (line.charAt(i) == '4') {
a += "2"
b += "2"
} else {
a += line.charAt(i)
b += "0"
}
}
println( s"Case #$cas: $a $b" );
}
}
}
I have found that extending App will give me either CTLE or TLE. Sometimes
resubmitting a CTLE solution will make it work. Here is an example that fails:
object Solution extends App {
var t = scala.io.StdIn.readLine().toInt
for( cas <- 1 to t) {
var line = scala.io.StdIn.readLine()
var a = ""
var b = ""
for( i <- 0 to line.size-1) {
if (line.charAt(i) == '4') {
a += "2"
b += "2"
} else {
a += line.charAt(i)
b += "0"
}
}
println( s"Case #$cas: $a $b" );
}
}
