The circle represents the field, and there are `x` flowers in the clockwise direction between Alice and Bob, and `y` flowers in the anti-clockwise direction between them. The game proceeds as follows: Alice takes the first turn. In each turn, a player must choose either the clockwise or anti-clockwise direction and pick one flower from that side. At the end of the turn, if there are no flowers left at all, the **current** player captures their opponent and wins the game. Given two integers, `n` and `m`, the task is to compute the number of possible pairs `(x, y)` that satisfy the conditions: Alice must win the game according to the described rules. The number of flowers `x` in the clockwise direction must be in the range `[1,n]`. The number of flowers `y` in the anti-clockwise direction must be in the range `[1,m]`. Return _the number of possible pairs_ `(x, y)` _that satisfy the conditions mentioned in the statement_. **Example 1:** ``` **Input:** n = 3, m = 2 **Output:** 3 **Explanation:** The following pairs satisfy conditions described in the statement: (1,2), (3,2), (2,1). ``` **Example 2:** ``` **Input:** n = 1, m = 1 **Output:** 0 **Explanation:** No pairs satisfy the conditions described in the statement. ``` **Constraints:** `1 <= n, m <= 105`", "public_test_cases": [ { "label": "Example 1", "input": "n = 3, m = 2", "output": "3 " }, { "label": "Example 2", "input": "n = 1, m = 1", "output": "0 " } ], "private_test_cases": [ { "input": [ 76449, 82807 ], "output": 3165256171 }, { "input": [ 37149, 7947 ], "output": 147611551 }, { "input": [ 65876, 54651 ], "output": 1800094638 }, { "input": [ 83462, 43930 ], "output": 1833242830 }, { "input": [ 85778, 70262 ], "output": 3013466918 }, { "input": [ 85146, 43396 ], "output": 1847497908 }, { "input": [ 31445, 22823 ], "output": 358834617 }, { "input": [ 15704, 32979 ], "output": 258951108 }, { "input": [ 74462, 73807 ], "output": 2747908417 }, { "input": [ 53354, 74360 ], "output": 1983701720 } ], "haskell_template": "flowerGame :: Int -> Int -> Int\nflowerGame n m ", "ocaml_template": "let flowerGame (n: int) (m: int) : int = ", "scala_template": "def flowerGame(n: Int,m: Int): Int = { \n \n}", "java_template": "class Solution {\n public long flowerGame(int n, int m) {\n \n }\n}", "python_template": "class Solution(object):\n def flowerGame(self, n, m):\n \"\"\"\n :type n: int\n :type m: int\n :rtype: int\n \"\"\"\n " }
