使用表示电影院座位图的二维数组。使用 3 种方法，用户输入询问席位价格，搜索一个阵列，然后找到第二个阵列中出现的第一个席位。我的问题是，如果"10"是输入，则输入正确。首先找到的座位号应为 1。相反，它找到了51号座位。问题可能出在我的第二种方法上，该方法搜索定价数组并保存位置以传递给第三种方法。
我尝试打印搜索以查看是否存在问题，它似乎没有读取每一行并跳过定价数组中的列。我尝试了不同的值来选择搜索的开始位置。

如果输入 10。它会说座位已确认，您的座位号是 1。如果您再次输入 10，它会说座位 2。
问题出在方法 2 for 循环上。分配第一个循环 "outer： for("，并为第二个循环中的中断条件添加 "break outer"。
