syntactic sugar when printing repeated multiplications
In C++, print a{5}
as a{5}
instead of aaaaa
.
In Python, if possible, map {num}
to UTF-8's exponents (super-scripts) in the text pretty-printing of the expressions: ⁰¹²³⁴⁵⁶⁷⁸⁹. It means that we also need to scan them: the text format is ok for input/output.
