Maximum Production (EITA) Solution — Codechef July Long Challenge


  • The first line contains an integer T, the number of test cases. Then the test cases follow.
  • Each test case contains a single line of input, four integers dd, x, y, z.


For each testcase, output in a single line the answer to the problem.


  • 1≤T≤5⋅10³
  • 1≤d<7
  • 1≤z<x<y≤18


Subtask #1 (100 points): Original constraints

Sample Input

1 2 3 1
6 2 3 1
1 2 8 1

Sample Output



Test Case 1: Using the first strategy, Chef does 2⋅7=14 units of work and using the second strategy Chef does 3⋅1+1⋅6=9 units of work. So the maximum amount of work that Chef can do is max(14,9)=14 units by using the first strategy.
