You are given a string num consisting of only digits. A string of digits is called balanced if the sum of the digits at even indices is equal to the sum of digits at odd indices.
Return true if num is balanced, otherwise return false.
Example 1:
Input: num = "1234"
Output: false
Explanation:
1 + 3 == 4, and the sum of digits at odd indices is 2 + 4 == 6.num is not balanced.Example 2:
Input: num = "24123"
Output: true
Explanation:
2 + 1 + 3 == 6, and the sum of digits at odd indices is 4 + 2 == 6.num is balanced.Constraints:
2 <= num.length <= 100num consists of digits onlyNeetCode
