Solving Time Based Key Value Store in go. Please try yourself first to solve the problem and submit your implementation to LeetCode before looking into solution.

## Problem Description

• If there are no values, it returns the empty string (`""`).

Example 1:

``````Input: inputs = ["TimeMap","set","get","get","set","get","get"], inputs = [[],["foo","bar",1],["foo",1],["foo",3],["foo","bar2",4],["foo",4],["foo",5]]
Output: [null,null,"bar","bar",null,"bar2","bar2"]
Explanation:
TimeMap kv;
kv.set("foo", "bar", 1); // store the key "foo" and value "bar" along with timestamp = 1
kv.get("foo", 1);  // output "bar"
kv.get("foo", 3); // output "bar" since there is no value corresponding to foo at timestamp 3 and timestamp 2, then the only value is at timestamp 1 ie "bar"
kv.set("foo", "bar2", 4);
kv.get("foo", 4); // output "bar2"
kv.get("foo", 5); //output "bar2"``````

Example 2:

``````Input: inputs = ["TimeMap","set","set","get","get","get","get","get"], inputs = [[],["love","high",10],["love","low",20],["love",5],["love",10],["love",15],["love",20],["love",25]]
Output: [null,null,null,"","high","high","low","low"]``````

Note:

1. All key/value strings are lowercase.

2. `1 <= timestamp <= 10^7`

3. set(string key, string value, int timestamp)

4. get(string key, int timestamp)

5. 1 <= timestamp <= 10^7
