"translatedContent": "「力扣挑战赛」中 `N*M` 大小的自行车炫技赛场的场地由一片连绵起伏的上下坡组成,场地的高度值记录于二维数组 `terrain` 中,场地的减速值记录于二维数组 `obstacle` 中。\n- 若选手骑着自行车从高度为 `h1` 且减速值为 `o1` 的位置到高度为 `h2` 且减速值为 `o2` 的相邻位置(上下左右四个方向),速度变化值为 `h1-h2-o2`(负值减速,正值增速)。\n\n选手初始位于坐标 `position` 处且初始速度为 1请问选手可以刚好到其他哪些位置时速度依旧为 1。请以二维数组形式返回这些位置。若有多个位置则按行坐标升序排列若有多个位置行坐标相同则按列坐标升序排列。\n\n**注意:** 骑行过程中速度不能为零或负值\n\n**示例 1**\n> 输入\b`position = [0,0], terrain = [[0,0],[0,0]], obstacle = [[0,0],[0,0]]`\n> \n> 输出:`[[0,1],[1,0],[1,1]]`\n> \n> 解释:\n> 由于当前场地属于平地,根据上面的规则,选手从`[0,0]`的位置出发都能刚好在其他处的位置速度为 1。\n\n**示例 2**\n> 输入\b`position = [1,1], terrain = [[5,0],[0,6]], obstacle = [[0,6],[7,0]]`\n> \n> 输出:`[[0,1]]`\n> \n> 解释:\n> 选手从 `[1,1]` 处的位置出发,到 `[0,1]` 处的位置时恰好速度为 1。\n\n\n**提示:**\n- `n == terrain.length == obstacle.length`\n- `m == terrain[i].length == obstacle[i].length`\n- `1 <= n <= 100`\n- `1 <= m <= 100`\n- `0 <= terrain[i][j], obstacle[i][j] <= 100`\n- `position.length == 2`\n- `0 <= position[0] < n`\n- `0 <= position[1] < m`",
