Problem statement

Given a string s containing (, ), <, >, |, and *, return whether it can form a valid, properly nested delimiter string.

The matching pairs are (), <>, and ||. Each * may independently be (, ), or the empty string. A single | can serve as the opening or closing bar according to its matching partner.

Function

isValidDelimiters(s: String) → boolean

Examples

Example 1

s = "<(*)>"return = true

Use the wildcard as the empty string; the remaining delimiters are nested.

Example 2

s = "<|*)|>"return = true

Use the wildcard as an opening parenthesis, producing <|()|>.

Example 3

s = "<(|>)"return = false

The delimiters cross instead of nesting.

Constraints

0 <= s.length <= 80.
s contains only (, ), <, >, |, and *.
