B'Moamen and Ezzat are playing a game. They create an array a of n non-negative integers where every element is less than 2^k . Moamen wins if a_1 , & , a_2 , & , a_3 , & , ldots , & , a_n ge a_1 oplus a_2 oplus a_3 oplus ldots oplus a_n . Here & denotes the bitwise AND operation, and oplus denotes the bitwise XOR operation. Please calculate the number of winning for Moamen arrays a . As the result may be very large, print the value modulo 1 ,000 ,000 ,007 ( 10^9 + 7 ). The first line contains a single integer t ( 1 <= t <= 5 ) -- the number of test cases. Each test case consists of one line containing two integers n and k ( 1 <= n <= 2 cdot 10^5 , 0 <= k <= 2 cdot 10^5 ). For each test case, print a single value -- the number of different arrays that Moamen wins with. Print the result modulo 1 ,000 ,000 ,007 ( 10^9 + 7 ). In the first example, n = 3 , k = 1 . As a result, all the possible arrays are [0,0,0] , [0,0,1] , [0,1,0] , [1,0,0] , [1,1,0] , [0,1,1] , [1,0,1] , and [1,1,1] . Moamen wins in only 5 of them: [0,0,0] , [1,1,0] , [0,1,1] , [1,0,1] , and [1,1,1] . '...
