LeetCode ProblemFind Positive Integer Solution for a Given Equation
Given a callable function f(x, y) with a hidden formula and a value z, reverse engineer the formula and return all positive integer pairs x and y where f(x,y) == z. You may return the pairs in any order. While the exact formula is hidden, the function is monotonically increasing, i.e.: The function interface is defined like this: We will judge your solution as follows:

# Example 2
Input
function_id = 1, z = 5
Output
[[1,4],[2,3],[3,2],[4,1]]
# Example 3
Input
function_id = 2, z = 5
Output
[[1,5],[5,1]]
Constraints
1 <= function_id <= 9
1 <= z <= 100
It is guaranteed that the solutions of f(x, y) == z will be in the range 1 <= x, y <= 1000.
It is also guaranteed that f(x, y) will fit in 32 bit signed integer if 1 <= x, y <= 1000.
