Examples of anagrams are dog, god; abac, baac; 123, 312 abab, aaba; dab, baad are not anagrams. INPUT : First line of the input is the number of test cases T. It is followed by T lines, each line has two space separated strings A and B; OUTPUT For each test case, print "YES" if they are anagrams, otherwise print "NO". (without quotes) Constraints 1 <= T <= 10 A and B both contain only lower case latin letters 'a' to 'z' and digits 0 to 9. Length of each string A and B does not exceed 5*10^5 (500000), Sample Input(Plaintext Link)  3 abcd bcda bad daa a1b2c3 abc123 Sample Output(Plaintext Link)  YES NO YES ==================== 4.
