WebFor each test case, print in one line the face values V1 ≤V2 ≤⋯≤Vk such that V1 +V2 +⋯+Vk = M. All the numbers must be separated by a space, and there must be no extra space at the end of the line. If such a solution is not unique, output the smallest sequence. If there is no solution, output "No Solution" instead. todd schnuck net worth
