CodeChefOpen on judge ↗

The Problem is pretty simple and straight forward. Calculate the sum of coefficients of (x+y)^n Input First line will contain the number of Test Cases T( 0 Output For each Test Case print single line having the sum of coefficients. If result exceed 1000000007 take mod with the result. Example Input: 5 10 20 30 40 50 Output: 1024 1048576 73741817 511620083 898961331
