Здравейте ,може ли решение на тази задача ,че малко се затруднявам.
The Master of the Mystic Arts is working on a very secret project in collaboration with a secret organization called The Prim****. They communicate via convoluted messages that can either contain a hidden 4-letter keyword or not. Since the Master of the Mystic Arts is very busy with his work, you are tasked with decoding the messages and informing him if a message contains the hidden word or not. You will receive the original message, the 4-letter keyword that might be hidden inside the message and the rules by which you can search for the word. Each rule consists of one letter from the 4-letter keyword, follow by four other letters it might be coded to. I.e., the rule t:e,d,o,b means the letter t from the keyword can exist in the messages as either e, d, o or b. The rules will be provided in the same order as the letters in the 4-letter keyword. After you check for the hidden keyword in the message you must output the index of the element where the keyword starts, or -1 Input Exactly 6 lines: the message the keyword first keyword letter rule second keyword letter rule third keyword letter rule fourth keyword letter rule Output Exactly one line: the index of the element the hidden word starts from - if the keyword is hidden in the message, or -1 otherwise Input gloprtbeinopl gorn g:a,b,c,d o:e,f,g,h r:i,j,k,l n:m,n,o,p Output 6 Explanation: You're looking for the hidden keyword gorn. g can be represented by either a, b, c or d, o can be represented by either e, f, g or h, etc. One valid representation of gorn is bein: g -> b o -> e r -> i n -> n Since the message contains bein and bein starts at index 6, you print 6.
