# 2496. Maximum Value of a String in an Array

Easy
The value of an alphanumeric string can be defined as:
• The numeric representation of the string in base `10`, if it comprises of digits only.
• The length of the string, otherwise.
Given an array `strs` of alphanumeric strings, return the maximum value of any string in `strs`.
Example 1:
Input: strs = ["alic3","bob","3","4","00000"]
Output: 5
Explanation:
- "alic3" consists of both letters and digits, so its value is its length, i.e. 5.
- "bob" consists only of letters, so its value is also its length, i.e. 3.
- "3" consists only of digits, so its value is its numeric equivalent, i.e. 3.
- "4" also consists only of digits, so its value is 4.
- "00000" consists only of digits, so its value is 0.
Hence, the maximum value is 5, of "alic3".
Example 2:
Input: strs = ["1","01","001","0001"]
Output: 1
Explanation:
Each string in the array has value 1. Hence, we return 1.
Constraints:
• `1 <= strs.length <= 100`
• `1 <= strs[i].length <= 9`
• `strs[i]` consists of only lowercase English letters and digits.

### 解題

func maximumValue(strs []string) int {
ans := 0
for _, str := range strs {
if s, err := strconv.Atoi(str); err == nil {
if s > ans { ans = s}
} else {
if len(str) > ans { ans = len(str)}
}
}
return ans
}
