Hi, I am trying this problem https://try.kotlinlang.org/#/Examples/Problems/Index%20of%20Maximum/Index%20of%20Maximum.kt
Here is my code

package maxindex

fun indexOfMax(a: IntArray): Int? {
    if (a.isEmpty())
    	return null
    return a.indexOf(a.max()!!)
}

I am getting all tests passed except testIndexOfMaximum6 and testIndexOfMaximum7. I can't find the bug. Pls help

sjthn: I think the test expects the last index with the maximum value. Try using lastIndexOf instead of indexOf.

Oh yes that's right. Thanks @marstran
