Hackerrank - Separate the Numbers Solution Beeze Aal 23.Jun.2020 A numeric string, , is beautiful if it can be split into a sequence of two or more positive integers, , satisfying the following conditions: 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. for any  (i.e., each element in the sequence is  more than the previous element). You are given a string S and a set of n substrings. Vowel substring hackerrank solution. In the second case, the second r is missing. Again using recursion we call the function itself to check if the remaining part of string that is "" which is an empty string starts with "13". Therefore it means we have successfully checked all part of our string and it forms a perfect sequence. We again increment our substring by 1 and it becomes "12". We again increment our substring by 1 and it becomes "13". 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). If you have already attempted the problem (solved it), you can access others code. What is the application of `rev` in real life? Problem Solution. 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. 1. In the second case, the second r is missing.
