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:
\n\nGiven two integers, n
and m
, the task is to compute the number of possible pairs (x, y)
that satisfy the conditions:
x
in the clockwise direction must be in the range [1,n]
.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.
\n
Example 1:
\n\n\nInput: n = 3, m = 2\nOutput: 3\nExplanation: The following pairs satisfy conditions described in the statement: (1,2), (3,2), (2,1).\n\n\n
Example 2:
\n\n\nInput: n = 1, m = 1\nOutput: 0\nExplanation: No pairs satisfy the conditions described in the statement.\n\n\n
\n
Constraints:
\n\n1 <= n, m <= 105
Alice 和 Bob 在一个长满鲜花的环形草地玩一个回合制游戏。环形的草地上有一些鲜花,Alice 到 Bob 之间顺时针有 x
朵鲜花,逆时针有 y
朵鲜花。
游戏过程如下:
\n\n给你两个整数 n
和 m
,你的任务是求出满足以下条件的所有 (x, y)
对:
x
必须在区间 [1,n]
之间。y
必须在区间 [1,m]
之间。请你返回满足题目描述的数对 (x, y)
的数目。
\n\n
示例 1:
\n\n\n输入:n = 3, m = 2\n输出:3\n解释:以下数对满足题目要求:(1,2) ,(3,2) ,(2,1) 。\n\n\n
示例 2:
\n\n\n输入:n = 1, m = 1\n输出:0\n解释:没有数对满足题目要求。\n\n\n

提示:
\n\n1 <= n, m <= 105
