Given an array of n elements, update all elements of given array to some minimum value x i.e, arr[i] = x (0 <= i < n), such that product of all elements of this new array is strictly greater than the product of all elements of the initial array.
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case contains an integer n denoting the size of the array. The next line contains the space separated array elements.
Print the minimum value for the new array such that product of elements of this new array is strictly greater than the product of all elements of the initial array.
