Problem: Gopal is climbing the stairs. He can jump 1 or 2 or 3 steps at a time.
He wants to climb N steps. In how many ways can he reach the Nth step?
As the answer can be too large Output it modulo 10^9+7.

Input:
First line of the input contains an integer T denoting the number of test cases.
Then T lines follow each line containing an integer N.

Output:
Output the required answer in a new line for each test case.

Constraints:
1 ≤ N ≤ 10^5

Explanation:
Test case: 2
There 7 ways of reaching 4^th step in the stairs:-

Solution (in PYTHON):

Solution:
li=[0,1,2,4,7]
mod=1000000007
for _ in range(int(raw_input())):
    m=int(raw_input())
    while len(li)-1<m:
        li.append(sum(li[-3:])%mod)
    print(li[m])
