Prevent stack overflow: Recursive calls cause the function call stack to grow continuously. Unlimited recursion could lead to stack space being exhausted, causing a stack  overflow error. Stack overflow results in program crash, and may even damage the operating system or hardware.\\n\\n2. Improve program readability: Excessively deep recursive calls make the function logic complex, which is unfavorable for the program's readability and maintenance. Limiting the recursion depth forces programmers to seek more concise and efficient design ideas, thus improving code quality.\\n\\n3. ..."}]}],"pr":"202fa612b8992373f10850b660525115ee5e91ed3129083c4713b60ef8939467"}
