Hackerrank Solutions. letters and an integer of the substring length K, determine the substring of that length that contains the most vowels. If we apply this brute force, it would take O(n*n) to generate all substrings and O(n) to do a check on each one. separateNumbers has the following parameter: The first line contains an integer , the number of strings to evaluate.Each of the next  lines contains an integer string  to query.eval(ez_write_tag([[468,60],'thepoorcoder_com-box-3','ezslot_18',102,'0','0'])); For each query, print its answer on a new line (i.e., either YES x where  is the smallest first number of the increasing sequence, or NO). Move end to find a valid window. If for any substring our sequential function returns True, we will break our loop and return "YES", If none of our substrings returns True we will return "NO", © 2021 The Poor Coder | Hackerrank Solutions - This allows us to assign a constant size signature to each of the substring of .
