// #Question - 2496. Maximum Value of a String in an Array

// 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.

// #Solution

function name(arr) {
  let newArr = [];
  arr.map((item) => {
    if (/^[0-9]+$/.test(item)) {
      newArr.push(item);
    } else {
      newArr.push(item.length);
    }
  });
  return Math.max(...newArr);
}

name(["alic3", "bob", "3", "4", "00000"]);
