Easy
428
64

You are given a string `s`, where every two consecutive vertical bars `'|'` are grouped into a pair. In other words, the 1st and 2nd `'|'` make a pair, the 3rd and 4th `'|'` make a pair, and so forth.

Return the number of `'*'` in `s`, excluding the `'*'` between each pair of `'|'`.

Note that each `'|'` will belong to exactly one pair.

Example 1:

```Input: s = "l|*e*et|c**o|*de|"
Output: 2
Explanation: The considered characters are underlined: "l|*e*et|c**o|*de|".
The characters between the first and second '|' are excluded from the answer.
Also, the characters between the third and fourth '|' are excluded from the answer.
There are 2 asterisks considered. Therefore, we return 2.```

Example 2:

```Input: s = "iamprogrammer"
Output: 0
Explanation: In this example, there are no asterisks in s. Therefore, we return 0.
```

Example 3:

```Input: s = "yo|uar|e**|b|e***au|tifu|l"
Output: 5
Explanation: The considered characters are underlined: "yo|uar|e**|b|e***au|tifu|l". There are 5 asterisks considered. Therefore, we return 5.```

Constraints:

• `1 <= s.length <= 1000`
• `s` consists of lowercase English letters, vertical bars `'|'`, and asterisks `'*'`.
• `s` contains an even number of vertical bars `'|'`.
