Find the smallest positive integer value that cannot be represented as sum of any subset of a given array | Returns the smallest number that cannot be represented as sum of subset of elements from set represented by sorted array arr [ 0. . n - 1 ].
Initialize result.
Traverse the array and increment ' res ' if arr [ i ] is smaller than or equal to ' res ' ..
Driver program to test above function"
How can the above be solved in Python?

=====
Can you provide a code to find the smallest positive integer value that cannot be represented as sum of any subset of a given array and the other steps required?
