codeforces#P1741A. Compare T-Shirt Sizes
Compare T-Shirt Sizes
Description
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).
