can be solved without 'regexp'
A slightly more robust test might include a balanced equation starting with something other than an opening bracket.
Test 3 might be
inStr = '3*(z*(a-(x+3))/(y))';
it doesn't work in some cases not included in test suite. for example:
inStr = '(z*(a-(x+3))/(y)*z)';
Seems to fail for inStr='(' , '((', etc.
I admit this is cheating, but I think it also stresses the need for more tests in the suite. Also, not all the cases should necessarily be visible, so you can't adapt a solution like this.
This solution fails for the input ')()', i.e. it returns true when it should return false.
This solution fails for the input '(()', i.e. it returns true when it should return false.
This entry is incorrect. It fails the simple case of:
Find the alphabetic word product
Getting the indices from a matrix
Create a Multiplication table matrix...
Given area find sides
Divisible by 2
Select every other element of a vector
Alphabetize by last name
Replace NaNs with the number that appears to its left in the row.
