C++中类的大小（Sizeof of Class in C++）
介绍作为面向对象的语言，C++有很多面向对象的特性。对于一个类，如果能够准确判断其占用大小，说明对面向对象有了深入的理解。sizeof是一个操作符，返回一个变量或者对象的大小。 在求职面试的过程中，很多情况下，会涉及到这个问题。所以，这里列举了不同情况下C++中类的大小，默认是在64位机器上的结果。
LeetCode Interleaving String
DescriptionGiven s1, s2, s3, find whether s3 is formed by the interleaving of s1 and s2. For example,Given:s1 = “aabcc”,s2 = “dbbca”, When s3 = “aadbbcbcac”, return true.When s3 = “aadbbbaccc”, return

LeetCode Perfect Squares
DescriptionGiven a positive integer n, find the least number of perfect square numbers (for example, 1, 4, 9, 16, …) which sum to n. For example, given n = 12, return 3 because 12 = 4 + 4 + 4; given n
LeetCode Longest Valid Parentheses
