Hi, here's your problem today. This problem was recently asked by Uber:

Imagine you are building a compiler. Before running any code, the compiler must check that the parentheses in the program are balanced. Every opening bracket must have a corresponding closing bracket. We can approximate this using strings.

Given a string containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid.

120 - 儿童编程热和计算机思维的培养 - computational-thinking-for-children.txt

AI（人工智能）的潮流轰轰烈烈而来，“深度学习”的字眼处处可以见， 面向儿童的编程课也成了热门课，好多家长都愿意付费让孩子去学。

先不说这些编程课质量如何，效果如何，就随便聊聊 “学习编程要不要早早开始”？

周末跟一个英国人工智能公司的小伙子聊了一下。 他是N大物理系毕业的，现在AI领域做得相当好， 不但公司里头的项目客户包括银行律所医院学校，而且自己业余做的项目客户里头有石油大公司。 他的观察是大学里头学计算机专业的，反而被困住了，在AI项目组里头往往成为边缘人员。而物理数学专业出来的，更擅长数学模型的思考和运算，可以在更高的一个层面上去思考问题，倒是项目的核心人员。他还举例说，90年代出国的好些华人其实都是数学很强的，可大多为了生计，转做码工，专职编程。现在AI热浪来了， 要转过来就觉得很吃力了。
