ZZULIOJ 1155: String comparison multiple instances, Java

Question description

Compare string sizes, but the comparison rules are different from the lexicographic rules. The new rules for character comparison are as follows: A < a < B < b < ………… < Z < z.

enter

The input data contains multiple test instances, each test instance occupies two lines, and each line has a string (containing only uppercase and lowercase letters, the length is less than 10000).

output

If the first string is less than the second string, output YES, otherwise, output NO.
Note: A < a < B < b < ………… < Z < z.

Sample inputCopy

abc
Bbc
Ab
a
ABcef
ABce

Sample outputCopy

YES
YES
NO
