给定句子的 Google CaSe
原文:https://www.geeksforgeeks.org/google-case-given-sentence/
给定一个句子，任务是在谷歌案例中重写。这是一种写作风格，我们将所有小写字母替换为大写字母，留下所有单词的首字母。
例:
Input : gEEks fOr GeeKs
Output : gEEKS fOR gEEKS
Input : I got intern at geeksforgeeks
Output : i gOT iNTERN aT gEEKSFORGEEKS
一个简单的解决方案就是把整个字符串转换成一个大写字母，然后遍历给定的字符串，同时遍历我们用小替换所有单词的首字母。

上述解决方案需要两次字符串遍历。一个有效的解决方案是在一次遍历中完成。这个想法是跟踪空间。在每个空格后，将字符打印到下方，否则打印到上方。
