Given a string, determine if a permutation of the string could form a palindrome. For example, "code"-> False,"aab"-> True,"carerac"-> True. Hint: Consider the palindromes of odd vs even length. What difference do you notice? Count the frequency of each character. If each character o...

567. Permutation in String i++ Given two strings s1 and s2, write a function toreturntrueifs2 contains the permutation of s1. In other words, one of the first string's permutations is the substring of the second string. Example 1: ...
Although the orbifolds of ℤ2-permutation-type are naturally Lorentzian, we find that the target space-times associated with larger permutation groups can be Lorentzian, Euclidean and even null $(\\hat{D}_j(\\sigma) = 0)$, with varying space-time dimensions, signature and symmetry in a ...

The first line contains a single integer t ( 1≤t≤1000 ) — the number of test cases. Then t test cases follow. The first line of each test case contains one integer n ( 1≤n≤40 ) — the length of the string. The second line of each test case contains the string s . It is...
