Hi Manan,
You are using ‘int’ data type which has a size of 4 byte, therefore its range is 2^31-1 which is approx 10^9. But in the question, the given range is 10^18. So, you should change your data type to long which has a size of 8 bytes. After that there’ll be another error when you store the digits into the array. Its a type casting error, try to figure it out. Ping me if you need help. :slight_smile:
