Vowel Anxiety CodeChef Solution

His teacher gave him the following problem to improve his vowel-identification skills:

There is a string SS of length NN consisting of lowercase English letters only. Utkarsh has to start from the first letter of the string.
Each time he encounters a vowel (i.e. a character from the set {a,e,i,o,u}{a,e,i,o,u}) he has to reverse the entire substring that came before the vowel.

Utkarsh needs help verifying his answer. Can you print the final string after performing all the operations for him?

Input Format

  • First line will contain¬†TT, number of test cases. Then¬†TT¬†test cases follow.
  • The first line of each test case contains¬†NN, the length of the string.
  • The second line contains¬†SS, the string itself.

Output Format

Test case 11: The first letter is a vowel, but there is no substring before it to reverse, so we leave it as it is. Next, we reverse abcd and the string becomes dcbaefghij. Next we reach the vowel i and reverse dcbaefgh to get the string hgfeabcdij.

Test case 22: Initially, we reverse bc and the string becomes cbadage. Next we reach the vowel a and reverse cbad to get the string dabcage. Finally we reach the vowel e and reverse dabcag to get the string gacbade.
