1. How do you design an api for bulk file uploading, lets say 1 GB. and where will you store it ? Assume 500 MB uploaded, got connection time out issue. As 500 mb is already uploaded, how can you control the client uploading only remaining part of the file.
2. Write a algo to find "([]){}" is well formed or not. Meaning, "([{]){}" is not well formed.
