There is an expression "ab" -> add (str (normal ('a')), normal ('b')) in the Some examples section but this expession gives "(ab)" instead of "ab".

Could someone explain this above?

Why the following code in c++ produced the following output? Is this correct?

code:

std::cout << pretty( add(any(), normal('a'))) << std::endl;

std::cout << pretty( add(normal('a'), any())) << std::endl;

std::cout << pretty( add(normal('a'), normal('b'))) << std::endl;

std::cout << pretty( add(normal('b'), normal('a'))) << std::endl;

output:

.

a

a

b

Is this ok?

Connect your account to your GitHub profile. Then change the pic on the GitHub profile, it will be used here as well.

Thanks for the anwser.
Could you give me a hint how to change the profile picture?

As long as there are values that are > INT MIN, it works.
Note that the values are compared to currentHigh, which is initially set to INT MIN. The comparison with 0 is with the position in the vector.

All test are for positive numbers.
How about negative numbers?

What if v will be consist negative only, it is works?

Also I have the same problem as decribed below:
Test Results:

STDERR:
