CodeChefOpen on judge ↗
Chef loves playing with numbers. He wants to know in how many ways can he represent a number $N$ as the sum of other numbers. Help chef find the number of ways. Let $K$ be the number of ways. Since $K$ can be large, output $K$ modulo 1000000007 ($10^9 + 7$). ###Input: - The first line will contain $T$, the number of testcases. Then the testcases follow. - Each testcase contains a single line
