# Basic Algorithm Scripting - Where do I Belong - Code failing for particular inputs

Tell us what’s happening:

Describe your issue in detail here.

Can you tell what’s wrong with my code. It works for every test example except the one that wrote below. And I am unable to understand. It happens for the input array which has duplicate elements.
Code so far

``````function getIndexToIns(arr, num) {
arr.sort();
let i;
// console.log(arr);
for (i=0; i<arr.length;i++){
if(arr[i]>=num&&arr[i]!=arr[i+1]){
continue;}
else if(arr[i]>=num&&arr[i]!=arr[i+1]){
return i;}
}
return i;
}

getIndexToIns([5, 3, 20, 3], 7); //Failed
getIndexToIns([10, 20, 30, 40, 50], 35) // passed
getIndexToIns([10, 20, 30, 40, 50], 30) // passed
getIndexToIns([40, 60], 50) // passed
getIndexToIns([3, 10, 5], 3) // passed

Challenge: Basic Algorithm Scripting - Where do I Belong

Are you sure?

It failed like this:

``````// running tests
getIndexToIns([10, 20, 30, 40, 50], 35) should return 3.
getIndexToIns([10, 20, 30, 40, 50], 30) should return 2.
getIndexToIns([40, 60], 50) should return 1.
getIndexToIns([3, 10, 5], 3) should return 0.
getIndexToIns([5, 3, 20, 3], 5) should return 2.
getIndexToIns([2, 20, 10], 19) should return 2.
// tests completed
``````

If you want to sort numbers you need to write callback function for sort() properly.
