Given a string (may contain both vowel and consonant letters), remove all consonants, then check if the resulting string is palindrome or not.
Examples:
Input : abcuhuvmnba Output : YES Explanation : The consonants in the string "abcuhuvmnba" are removed. Now the string becomes "auua". Input : xayzuezyax Output : NO Input : bkldhgcj Output : -1
Approach:
Remove all the consonants in the string. Check if the vowel string is a palindrome. If it is a palindrome print YES, else print NO. If string contains no vowels, then print -1.
Below is the Python implementation:
# Python program to check if given # string is vowel Palindrome # Function to check if a given string is a vowel def vowel(c): # creating a list of vowels v = list("aeiou") # if the character is a vowel return True if c in v: return True return False # Function to check if a vowel # string is palindrome def palindrome(s): # create a empty list v = [] # append all vowels into the list for i in s: if vowel(i):v.append(i) # if the length of the vowel # string is 0 then print -1 if len(v)== 0: print("-1") # else check if it is a palindrome else: # create a reversed string x = v[::-1] # initialize a flag f = 1 for i in range(len(x)): # if the characters are not the same if x[i]!= v[i]: # set the flag to 0 f = 0 break if f == 1: print("YES") else: print("NO") # Driver Code s = 'abcuhuvmnba' # calling the main function palindrome(s.strip())
Output:
YES
