    k = int(input())
for i in range (k):
    l = int(input())
    ways = [0]*100001
    ways[0] = 1
    for x in [1,2,5,10,20,50,100,200]:
        for i in range(x, 100001):
            ways[i] += ways[i-x]
    print (ways[l]%(10**9+7))

    I am getting correct answers for testcases 0 1 and 3, but everything is timeout. How can I optimize this? Thanks.
