Timer is Running

Implement different operations on Treemap. Operations will be performed by different types of queries.
A query can be of four types:
1. a x y (adds an entry with key x and value y to the Treemap)
2. b x (print value of  x if present in the Treemap else print -1. )
3. c (prints the size of the Treemap)
4. d x ( removes an entry with key x from the map )
5. e (print map sorted by key)

Example 1:

a 1 2 a 66 3 b 66 d 1 c e

3 1 66

There are five queries. Queries are performed in this order
1. a 1 2    --->  map has a key 1 with value 2 
2. a 66 3   ---> map has a key 66 with value 3
3. b 66     ---> prints the value of key 66 if its present in the map ie 3.
4. d 1      ---> removes an entry from map with key 1
5. c        ---> prints the size of the map ie 1
6. e        ---> prints the map sorted by key


Example 2:

a 1 66 b 5 c e

-1 1 1

There are three queries. Queries are performed in this order
1. a 1 66   ---> adds a key 1 with a value of 66 in the map
2. b 5      --->  since the key 5 is not present in the map hence -1 is printed.
3. c        ---> prints the size of the map ie 1 
4. e        ---> prints the map sorted by key

Your Task:
You are required to complete the following functions:
add_Value : Takes HashMap, x, y as arguments and maps x as key and y as its value. Does not return anything.
find_value : Takes HashMap and x as arguments. If HM contains x key then return the value, else return -1.
getSize : Takes HashMap as argument and just returns its size.
removeKey : Takes HashMap and x as arguments and removes x if it exists. Does not return anything.
: Takes HashMap as argument and prints the keys that are sorted. Don't print newline.
