Consider a group of $5011$ friends and a particular person in the group (say L). L has a message to spread around. Define a “whisper” as an instance where a friend passes the message to another friend. Considering all friends to be distinct, L is interested in finding out the number of sequences of $999983$ “whispers” after which he will eventually get the message back. Calculate the answer modulo $1000000007$.

Note:

1. After a whisper, if A passed the message to B, then only B can whisper to others since only he has the message. Others can’t.

2. During the sequence of whispers, there can be a point in time where A would get the message after less than $999983$ whispers. In that case, he again should pass the message to others in order to complete a total of $999983$ whispers
