Asked in companies
Ninja is learning a new but strange language known as Alien Language. Alien language possesses the same alphabets as of English language, but their order is different. The order of letters are given as ‘ORDER’ string. Ninja has ‘N’ words in the ‘WORDS’ array. Ninja’s task is to check whether the words of ‘WORDS’ are sorted lexicographically in this alien language or not.
Note: ‘ORDER’ consists of all 26 letters of English alphabet.
For Example
If ‘WORDS’ = ["word","world","row"], ‘ORDER’ = "worldabcefghijkmnpqstuvxyz",the answer will be ‘NO’ as first and second words are not lexicographically sorted as ‘l’ comes before ‘d’ in alien language.
