Given a string, rearrange characters of the given string such that the vowels and consonants occupy alternate position. If string can not be rearranged in desired way, print “no such string”. The order of vowels with respect to each other and the order of consonants with respect to each other should be maintained.
If more than one required strings can be formed, print the lexicographically smaller.
Input : geeks Output : gekes Input : onse Output : nose There are two possible outcomes "nose" and "ones". Since "nose" is lexicographically smaller, we print it.
- Count number of vowels and consonants in given string.
- If difference between counts is more than one, return “Not Possible”.
- If there are more vowels than consonants, print first vowel first and recur for remaining string.
- If there are more consonants than vowels, print first consonant first and recur for remaining string.
- If counts are same, compare first vowel with first consonant and print the smaller one first.
Time Complexity: O(n), where ‘n’ the is length of the string
