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:-

1+1+1+1
1+1+2

Solution (in PYTHON):

Solution:
t = int(raw_input())
d = [1, 1, 2, 4]
u = pow(10, 9) + 7
while(t):
    n = int(raw_input())
    if n >= len(d):
	    for i in range(len(d), n+1):
		    d.insert(i, (d[i-1] + d[i-2] + d[i-3]))
    if d[n] >= u:
        print d[n] % u
    else:
	    print d[n]
    t -= 1
