Can you solve this real interview question? Shortest Palindrome - You are given a string s. You can convert s to a palindrome by adding characters in front of it. Return the shortest palindrome you can find by performing this transformation. Example
Output: [true,false,false,true,true] Explanation: queries[0] : substring = "d", is palidrome. queries[1] : substring = "bc", is not palidrome. queries[2] : substring = "abcd", is not palidrome after replacing only 1 character. queries[3] : substring = "abcd", could be changed...

palindrome最大的特性就是对称,按长度的奇偶可以分为str,char,reverse(str)还有 str,reverse(str)型。 我们有一个str,在i这个位置进行切分,得到的前半部分是一个palindrome. 比如”lls”, 变成”ll”, “s”. 已知”ll”是palindrome,我们只需要知道reverse(“s”) 放到前边就可以了。
