( 26480 ) B Alphabetical Strings PROGRAMMING greedy implementation strings

B'A string s of length n ( 1 <= n <= 26 ) is called alphabetical if it can be obtained using the following algorithm: In other words, iterate over the n first letters of the Latin alphabet starting from 'a ' and etc. Each time we prepend a letter to the left of the string s or append a letter to the right of the string s . Strings that can be obtained in that way are alphabetical. For example, the following strings are alphabetical: "a", "ba", "ab", "bac" and "ihfcbadeg". The following strings are not alphabetical: "z", "aa", "ca", "acb", "xyz" and "ddcba". From the given string, determine if it is alphabetical. The first line contains one integer t ( 1 <= t <= 10^4 ) -- the number of test cases. Then t test cases follow. Each test case is written on a separate line that contains one string s . String s consists of lowercase letters of the Latin alphabet and has a length between 1 and 26 , inclusive. Output t lines, each of them must contain the answer to the corresponding test case. Output YES if the given string s is alphabetical and NO otherwise. You can output YES and NO in any case (for example, strings yEs, yes, Yes and YES will be recognized as a positive answer). The example contains test cases from the main part of the condition. '...
