( 25408 ) B AND 0, Sum Big PROGRAMMING bitmasks combinatorics math #adonay

B'Baby Badawy 's first words were "AND 0 SUM BIG", so he decided to solve the following problem. Given two integers n and k , count the number of arrays of length n such that: Since the answer can be very large, print its remainder when divided by 10^9+7 . The first line contains an integer t ( 1 <= t <= 10 ) -- the number of test cases you need to solve. Each test case consists of a line containing two integers n and k ( 1 <= n <= 10^{5} , 1 <= k <= 20 ). For each test case, print the number of arrays satisfying the conditions. Since the answer can be very large, print its remainder when divided by 10^9+7 . In the first example, the 4 arrays are: '...
