CF1741A Compare T-Shirt Sizes

Two T-shirt sizes are given: $ a $ and $ b $ . The T-shirt size is either a string M or a string consisting of several (possibly zero) characters X and one of the characters S or L. For example, strings M, XXL, S, XXXXXXXS could be the size of some T-shirts. And the strings XM, LL, SX are not sizes. The letter M stands for medium, S for small, L for large. The letter X refers to the degree of size (from eXtra). For example, XXL is extra-extra-large (bigger than XL, and smaller than XXXL). You need to compare two given sizes of T-shirts $ a $ and $ b $ . The T-shirts are compared as follows: - any small size (no matter how many letters X) is smaller than the medium size and any large size; - any large size (regardless of the number of letters X) is larger than the medium size and any small size; - the more letters X before S, the smaller the size; - the more letters X in front of L, the larger the size. For example: - XXXS < XS - XXXL > XL - XL > M - XXL = XXL - XXXXXS < M - XL > XXXS

The first line of the input contains a single integer $ t $ ( $ 1 \le t \le 10^4 $ ) — the number of test cases. Each test case consists of one line, in which $ a $ and $ b $ T-shirt sizes are written. The lengths of the strings corresponding to the T-shirt sizes do not exceed $ 50 $ . It is guaranteed that all sizes are correct.

For each test case, print on a separate line the result of comparing $ a $ and $ b $ T-shirt sizes (lines "<", ">" or "=" without quotes).
