Given a set of hotels and its guests reviews, sort the hotels based on a list of words specified by a user. The criteria to sort the hotels should be how many times the words specified by the user is mentioned in the hotel reviews. Input: The first line contains a space-separated set of words which we want to find mentions in the hotel reviews. The second line contains one integer M, which is the number of reviews. This is followed by M+M lines, which alternates an hotel ID and a review belonging to that hotel. Output: A list of hotel IDs sorted, in descending order, by how many mentions they have of the words specified in the input. Notes: * The words to be find will always be single words like 'breakfast' or 'noise*. Never double words like 'swimming pool'. * Hotel ID is a 4-byte integer * Words match should be case-insensitive * Dots and commas should be ignored. * If a word appears in a review twice, it should count twice. * If two hotels have the same number of mentions, they should be sorted in the output based on their ID, smallest ID first. * In case one or more test cases time out, consider revisiting the runtime complexity of your algorithms

Given a list of numbers as input, e.g. : 25626 25757 24367 24267 16 100 2 7277 Output a delta encoding for the sequence. In a delta encoding, the first element is reproduced as-is. Each subsequent element is represented as the numeric difference from the element before it. E.g. for the sequence above, the delta encoding would be: 25626 131 -1390 -100 -24251 84 -98 7275 However, if a difference value does not fit in a single signed byte, i.e. -127 <= x <= 127, then, instead of the difference, we would like to use an escape token, printing it. This will denote that the value following the escape token is a full four-byte difference value, rather than a one-byte difference value. For this exercise, well declare -128 as the escape token. Following the same example above, the final output would be: 25626 -128 131 -128 -1390 -100 -128 -24251 84 -98 -128 7275
