| 13 | +## Problem Statement |
| 14 | + |
| 15 | +There are `n` kids with candies. You are given an integer array `candies`, where each `candies[i]` represents the number of candies the ith kid has, and an integer `extraCandies`, denoting the number of extra candies that you have. |
| 16 | + |
| 17 | +Return a boolean array `result` of length `n`, where `result[i]` is `true` if, after giving the ith kid all the `extraCandies`, they will have the greatest number of candies among all the kids, or `false` otherwise. |
| 18 | + |
| 19 | +**Example 1:** |
| 20 | + |
| 21 | +Input: `candies = [2,3,5,1,3]`, `extraCandies = 3` |
| 22 | + |
| 23 | +Output: `[true,true,true,false,true]` |
| 24 | + |
| 25 | +Explanation: If you give all `extraCandies` to: |
| 26 | +- Kid 1, they will have `2 + 3 = 5` candies, which is the greatest among the kids. |
| 27 | +- Kid 2, they will have `3 + 3 = 6` candies, which is the greatest among the kids. |
| 28 | +- Kid 3, they will have `5 + 3 = 8` candies, which is the greatest among the kids. |
| 29 | +- Kid 4, they will have `1 + 3 = 4` candies, which is not the greatest among the kids. |
| 30 | +- Kid 5, they will have `3 + 3 = 6` candies, which is the greatest among the kids. |
| 31 | + |
| 32 | +**Example 2:** |
| 33 | + |
| 34 | +Input: `candies = [4,2,1,1,2]`, `extraCandies = 1` |
| 35 | + |
| 36 | +Output: `[true,false,false,false,false]` |
| 37 | + |
| 38 | +Explanation: There is only `1` extra candy. |
| 39 | +Kid 1 will always have the greatest number of candies, even if a different kid is given the extra candy. |
| 40 | + |
| 41 | +**Example 3:** |
| 42 | + |
| 43 | +Input: `candies = [12,1,12]`, `extraCandies = 10` |
| 44 | + |
| 45 | +Output: `[true,false,true]` |
| 46 | + |
| 47 | +**Constraints:** |
| 48 | + |
| 49 | +- `n == candies.length` |
| 50 | +- `2 <= n <= 100` |
| 51 | +- `1 <= candies[i] <= 100` |
| 52 | +- `1 <= extraCandies <= 50` |
| 53 | + |
| 54 | +## Solutions |
| 55 | + |
| 56 | +### Approach |
| 57 | + |
| 58 | +To determine if each kid can have the greatest number of candies after receiving `extraCandies`, follow these steps: |
| 59 | + |
| 60 | +1. **Find the Maximum Candies:** |
| 61 | + - Traverse through the `candies` array to find the maximum number of candies any kid currently has. |
| 62 | + |
| 63 | +2. **Check Each Kid's Condition:** |
| 64 | + - Iterate through the `candies` array again. |
| 65 | + - For each kid, check if adding `extraCandies` to their current candies makes their total candies equal to or greater than the maximum number found. |
| 66 | + - Store `true` if the condition is met, otherwise store `false`. |
| 67 | + |
| 68 | +### Java |
| 69 | + |
| 70 | +```java |
| 71 | + |
| 72 | +class Solution { |
| 73 | + public List<Boolean> kidsWithCandies(int[] candies, int extraCandies) { |
| 74 | + int maxCandies = 0; |
| 75 | + for (int candy : candies) { |
| 76 | + maxCandies = Math.max(maxCandies, candy); |
| 77 | + } |
| 78 | + |
| 79 | + List<Boolean> result = new ArrayList<>(); |
| 80 | + for (int candy : candies) { |
| 81 | + result.add(candy + extraCandies >= maxCandies); |
| 82 | + } |
| 83 | + |
| 84 | + return result; |
| 85 | + } |
| 86 | + |
| 87 | +} |
| 88 | +``` |
| 89 | + |
| 90 | +### Python |
| 91 | +```Python |
| 92 | +class Solution: |
| 93 | + def kidsWithCandies(self, candies: List[int], extraCandies: int) -> List[bool]: |
| 94 | + maxCandies = max(candies) |
| 95 | + result = [] |
| 96 | + |
| 97 | + for candy in candies: |
| 98 | + result.append(candy + extraCandies >= maxCandies) |
| 99 | + |
| 100 | + return result |
| 101 | +``` |
