选项A(选择结构):if-then-else语句根据条件I的值不同,执行不同的分支(X=X+1或X=X*2),属于典型的分支控制,符合选择结构定义。选项B(循环结构):代码中没有出现循环关键词(如For/While)和重复执行逻辑,与循环无关。选项C(顺序结构):代码存在条件判断打破顺序执行的特点,故排除。选项D(树型结构):“树型...

But there are times when the check is used only in this function and nowhere else; I don't like polluting my class with random helper functions used only to support this function. Doing so negatively affects maintainability—what if someone else calls this function and I need to make a chan...
