## Problem Statement

- The main goal of this task is to implement three generic functions:
,`valid_sum`

and`sum_of_one`

.`sum_of_all`

- The
is kind of a helper function which will create an array of valid non-negative intergers from the given 2d matrix.`valid_sum`

- One of the primary functions is
, which computes all the possible subsets from an array of non-negative integers whose sum is equal to the provided integer sum.`sum_of_one`

- Next comes the final function which is
. This function computes all the possible subsets from an array of non-negative integers whose sum is equal to all valid non-negative integer elements from the given 2d matrix.`sum_of_all`

actually Iâ€™m getting these errors in test
