Question

The input to this method is supposedly an ArrayList of integers
    that ranges from 1 to 100, however this is not exactly the case.
    Sometimes, there will be gaps in the range for example, the range
    could be: [1 2 ... 7 8 ... 99 100], with missing ranges in between.
    Find all the missing numbers from the range, add them to an ArrayList,
    return the ArrayList.
------------------------

Below is my code that is failing. It is returning the correct missing numbers but is not going passed the last number  from the array. so [4,5,14,16,23,76,89] It is placing all of the missing numbers up to 88 when it should be going to 100

------------------------

public ArrayList<Integer> solution(ArrayList<Integer> nums) {
ArrayList<Integer> result = new ArrayList<Integer>();
int count = 0;

for(int i = 0;i<nums.size()-1;i++){

for(int j = nums.get(i)+1;j<nums.get(i+1);j++){
count++;
result.add(j);
}

}
return result;
}

Follow-up Question

The solution should only return the missing numbers from 1-100. The original numbers from the given array should not be included in the return. How can I only return the missing numbers?
