Add Spaces Around Parentheses in a String
Given a string s, return it with every '(' and ')' set apart from its neighbours by exactly one space, every run of spaces reduced to one space, and no space at either end.
Examples
Example 1
{
"s": "(a(b)c)"
}Output: "( a ( b ) c )"
Example 2
{
"s": "hello(world)"
}Output: "hello ( world )"
