Question 17:

String str = "a black cat sat on a table";

int counter = 0;

for (int i = 0; i < str.length() - 1; i++) {

    if (str.substring(i, i + 1).equals("a") && !str.substring(i + 1, i + 2).equals("b")){
        counter++;
    }
}

System.out.println(counter);

{
    int lenCount = 0;
    int maxLen = 0;

    for (int val : nums){
