Toggle Consonants Adjacent to Vowels

 Coding Problem Keys 

 Toggle Consonants Adjacent to Vowels 

 Problem Statement 

The program must accept a string S containing only alphabets both in lower and upper case. The program must toggle the case of the consonants (non-vowels) adjacent to the vowels.

 Boundary Condition(s) 

2 <= Length of the string S <= 100

 Input Format 

The first line contains the string value S.

 Output Format 

The first line contains the toggle consonants between vowels.

 Example Input/Output 1 

 Input 

adJaeCent

 Output 

aDjaeceNt

 Example Input/Output 2 

 Input 

mAtRIMonY

 Output 

MATrImoNY

s=input().strip()
vow="AEIOUaeiou"
for i in range(len(s)):
    if s[i] not in vow and ((i>0 and s[i-1] in vow) or (i+1<len(s) and s[i+1] in vow)):
        print(s[i].swapcase(),end="")
    else:
        print(s[i],end="")
