This code passed test in task. But there is small bug if you use same string. For example (i will use only 5 even it is asked for 10):
1
12
123
1
12345
You will get answer index number 0 because index 0 and index 3 have the same value. How to avoid this ?
Edit:
In Level 7 Lesson 10 there is an article which explains use of indexOf() - and it is working as it is supposed to. But still is there other solution to this problem :)Bug in program that passed checking
