理解遞歸（see me see me）

1.項目源碼（加載菜單樹） 

 private List<MenuInfoCopier> getMemus(MenuInfo menuInfo, List<MenuInfoCopier> totalMenuList) {
        if (totalMenuList == null) {
            totalMenuList = new ArrayList<>();
        }
        MenuInfoCopier currentMenuInfoCopier = getMenuInfoCopier(menuInfo);
        totalMenuList.add(currentMenuInfoCopier);
        if (menuInfo.getMenuList().size() > 0) {
            for (MenuInfo childMenuInfo : menuInfo.getMenuList()) {
                totalMenuList = getMemus(childMenuInfo, totalMenuList);
            }
        }
        return totalMenuList;
    }

2.遞歸的執行流程：

從上面可以看出，遞歸主要有兩個階段，遞推分解任務與任務的迴歸

別人寫的太好，我都插不上嘴，只能大喊“666”！
