    "task_description": "Alice and Bob are playing a turn-based game on a circular field surrounded by flowers. 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`",
