    My Solution in kotlin covering All test cases.

    fun marsExploration(s: String): Int {
    var counter = 0
    val lastIndex = s.length - 1
    for(i in 0..s.length step 3) {
        
        if (i > lastIndex) break
        
        if (s[i] != 'S') counter++
        if (s[i + 1] != 'O') counter++
        if (s[i + 2] != 'S') counter++
    }

    return counter
}
