package main

// 3232. Find if Digit Game Can Be Won
// You are given an array of positive integers nums.

// Alice and Bob are playing a game. 
// In the game, Alice can choose either all single-digit numbers or all double-digit numbers from nums, and the rest of the numbers are given to Bob. 
// Alice wins if the sum of her numbers is strictly greater than the sum of Bob's numbers.

// Return true if Alice can win this game, otherwise, return false.

// Example 1:
// Input: nums = [1,2,3,4,10]
// Output: false
// Explanation:
// Alice cannot win by choosing either single-digit or double-digit numbers.

// Example 2:
// Input: nums = [1,2,3,4,5,14]
// Output: true
// Explanation:
// Alice can win by choosing single-digit numbers which have a sum equal to 15.

// Example 3:
// Input: nums = [5,5,5,25]
// Output: true
// Explanation:
// Alice can win by choosing double-digit numbers which have a sum equal to 25.

// Constraints:
//     1 <= nums.length <= 100
//     1 <= nums[i] <= 99
