Stack overflow: Recursive calls lead to continuous growth of the function call stack, which  requires memory allocation for the stack each time. When the recursion depth is too large, the stack space may not be sufficient to accommodate more calls, resulting in a stack overflow. This error affects the normal operation of the program and may even cause the program to crash.\\n\\n2. Performance issues: Recursive calls lead to a large amount of redundant calculations because each call needs to recover previous calculation results from the stack. When solving large-scale problems, recursive calls may result in poor performance. Modern computers have\\n"}]}],"pr":"251c6f38ae50754595f5a6547a420c2743750df8de7af89eee9cd87894f428e5"}
