why it gives an error?

Question

when i run the following code in sololearn, it gives errors.
fun main(args: Array<String>) {
var arr : Array<Int>= arrayOf(1, 2, 3);
println(arr[0]);
println(arr[1]);
println(arr[2]);
}
but when i run it after adding a space before "=" then it gives no error.

fun main(args: Array<String>) {
var arr : Array<Int> = arrayOf(1, 2, 3);
println(arr[0]);
println(arr[1]);
println(arr[2]);
}

Answer 1

Splitting input into tokens has no knowledge of how they are going to be used so it always looks for the longest valid string. Since >= is a token for greater equal, that will always be returned over the greater and the equal tokens you expected. A smarter compiler could discover that and adjust in the syntax check, but the 1.3 version generates the same error (SoloLearn is 1.1).

Answer 2

The kotlin compiler seems to confuse >= with a greater than operator.
[Edit] Greater equal🤦‍♂️
