{ "id": 2916, "name": "check_if_it_is_possible_to_split_array", "difficulty": "Medium", "link": "https://leetcode.com/problems/check-if-it-is-possible-to-split-array/", "date": "1690675200000", "task_description": "You are given an array `nums` of length `n` and an integer `m`. You need to determine if it is possible to split the array into `n` arrays of size 1 by performing a series of steps. An array is called **good** if: The length of the array is **one**, or The sum of the elements of the array is **greater than or equal** to `m`. In each step, you can select an existing array (which may be the result of previous steps) with a length of **at least two** and split it into **two **arrays, if both resulting arrays are good. Return true if you can split the given array into `n` arrays, otherwise return false. **Example 1:** **Input:** nums = [2, 2, 1], m = 4 **Output:** true **Explanation:** Split `[2, 2, 1]` to `[2, 2]` and `[1]`. The array `[1]` has a length of one, and the array `[2, 2]` has the sum of its elements equal to `4 >= m`, so both are good arrays. Split `[2, 2]` to `[2]` and `[2]`. both arrays have the length of one, so both are good arrays. **Example 2:** **Input:** nums = [2, 1, 3], m = 5 **Output:** false **Explanation:** The first move has to be either of the following: Split `[2, 1, 3]` to `[2, 1]` and `[3]`. The array `[2, 1]` has neither length of one nor sum of elements greater than or equal to `m`. Split `[2, 1, 3]` to `[2]` and `[1, 3]`. The array `[1, 3]` has neither length of one nor sum of elements greater than or equal to `m`. So as both moves are invalid (they do not divide the array into two good arrays), we are unable to split `nums` into `n` arrays of size 1. **Example 3:** **Input:** nums = [2, 3, 3, 2, 3], m = 6 **Output:** true **Explanation:** Split `[2, 3, 3, 2, 3]` to `[2]` and `[3, 3, 2, 3]`. Split `[3, 3, 2, 3]` to `[3, 3, 2]` and `[3]`. Split `[3, 3, 2]` to `[3, 3]` and `[2]`. Split `[3, 3]` to `[3]` and `[3]`. **Constraints:** `1 <= n == nums.length <= 100` `1 <= nums[i] <= 100` `1 <= m <= 200`", "public_test_cases": [ { "label": "Example 1", "input": "nums = [2, 2, 1], m = 4", "output": "true " }, { "label": "Example 2", "input": "nums = [2, 1, 3], m = 5", "output": "false " }, { "label": "Example 3", "input": "nums = [2, 3, 3, 2, 3], m = 6", "output": "true " } ], "private_test_cases": [ { "input": [ [ 18, 69, 96, 19, 19, 24, 75, 93 ], 37 ], "output": true }, { "input": [ [ 71, 4, 31, 26, 15, 30, 31, 23, 100, 84, 50, 17, 61, 40, 49, 52, 84, 86, 15, 37, 81, 92, 80, 30, 78, 74, 99, 60, 9, 27, 41, 9, 71, 67, 89, 74, 24, 3, 95, 49, 35, 76, 19, 48, 15, 40, 3, 27, 17, 26, 83, 52, 63, 19, 70, 22, 84, 97, 38, 4, 68, 60, 30, 68, 64, 56 ], 107 ], "output": true }, { "input": [ [ 87, 25, 44, 89, 7, 51, 1, 82, 2, 57, 2, 75, 76, 55, 50, 51, 8, 42, 93, 25, 69, 86, 36, 50, 81, 84, 43, 65, 70, 9, 48, 82, 91, 32, 8, 59, 21, 43, 31, 44, 39, 48, 71, 53, 34, 1, 49, 65, 25, 36, 50, 57, 16, 65, 43, 100, 1, 8, 27, 58, 53 ], 122 ], "output": true }, { "input": [ [ 67, 12, 92, 44, 8, 80, 61, 28, 50, 78, 35, 80, 43, 28, 8, 53, 81, 35, 21, 79, 30, 69, 54, 77, 47, 12, 15, 22, 80, 93, 83, 91, 95, 13, 10, 25, 86, 43, 97, 20, 27, 40, 10, 38, 11, 57, 15, 44, 64, 69, 56, 98, 94, 2, 31, 61, 27, 97, 76, 36, 56, 50, 64, 75, 57, 100, 78, 82, 56, 6, 15, 66, 8, 13, 70, 68, 50, 82, 4, 29, 14, 87, 27, 68, 69, 58, 45, 30, 35, 18 ], 187 ], "output": true }, { "input": [ [ 64, 44, 32, 43, 20, 52, 35, 93, 3, 33, 80, 70, 16, 62, 37, 89, 58, 27, 18, 5, 18, 66, 6, 49, 21, 62, 21, 16, 36, 50, 16, 50, 81, 97, 100, 5, 26, 53, 39, 28, 70, 82, 25, 81, 20, 35, 83, 54, 84, 31, 14, 65, 31, 19, 91, 1, 100, 69, 67, 78, 93, 42, 63, 71, 83, 16, 58, 66, 32, 95, 71, 59, 18, 87, 8, 14, 49, 93, 41, 45, 47, 31, 47, 69, 28, 66, 82, 94, 85, 74, 32, 21, 11, 38, 3, 30, 85, 72 ], 130 ], "output": true }, { "input": [ [ 50, 47, 14, 22, 1, 63, 74, 56, 25, 90, 74, 37, 88, 68, 88, 8, 41, 14, 4, 100, 35, 49 ], 152 ], "output": true }, { "input": [ [ 25, 40, 72, 94, 35, 73, 22, 4, 89, 42, 21, 98, 72, 55, 82, 71, 62, 21, 2, 99, 58, 36, 41, 99, 15, 61, 57, 94, 56, 25, 35, 30, 19, 68, 18, 14, 61, 40, 23, 52, 31, 48, 14, 35, 91, 62, 25, 21, 77, 96, 57, 69, 80, 27, 67, 23, 9, 38, 38, 86, 94, 16, 14, 64, 48, 89, 19, 21, 91, 24, 19, 58, 73, 76, 60, 60, 79, 35, 20, 67, 67 ], 186 ], "output": false }, { "input": [ [ 48, 81, 54, 60, 65, 99, 90, 22, 7, 80, 41, 49 ], 83 ], "output": true }, { "input": [ [ 47, 28, 38, 52, 96, 31, 17, 56, 47, 75, 75, 60, 70, 31, 53, 25, 64, 51, 33, 80, 79, 10, 10 ], 192 ], "output": false }, { "input": [ [ 92, 17, 34, 46, 6, 27, 60, 62, 77, 77, 36, 12, 49, 73, 15, 45, 26, 62, 11, 11, 1, 49, 24, 78, 29, 15, 40, 95, 73, 77, 11 ], 187 ], "output": false } ], "haskell_template": "canSplitArray :: [Int] -> Int -> Bool\ncanSplitArray nums m ", "ocaml_template": "let canSplitArray (nums: int list) (m: int) : bool = ", "scala_template": "def canSplitArray(nums: List[Int],m: Int): Boolean = { \n \n}", "java_template": "public static boolean canSplitArray(List nums, int m) {\n\n}", "python_template": "class Solution(object):\n def canSplitArray(self, nums, m):\n \"\"\"\n :type nums: List[int]\n :type m: int\n :rtype: bool\n \"\"\"\n " }
