python doesn't have any library for ordered map and ordered set. We can install sortedContainers module in our pc for that. Please include this module. It would be very helpful for all who code in python.

160762368 — accepted (str)

160761953 — tle (int)

both solution are same the only difference is the key in first is string and in 2nd the key is int which is causing tle .....
