Software Engineer

Aakash is a member of Ninja club. He has a weird family structure. Every male member (M) gives birth to a male child first and then a female child, whereas every female (F) member gives birth to a female child first and then to a male child. Aakash analyses this pattern and wants to know what will be the Kth child in his Nth generation. Can you help him?

A sample generation tree is shown, where ‘M’ denotes the male member and ‘F’ denotes the female member. 

Note

The generation tree starts with a male member i.e. Aakash. 
Every member has exactly two children. 
The given N and K will always be valid. 

You are given a string STR of length N. Your task is to remove all the vowels present in that string and print the modified string.

English alphabets ‘a’, ‘e’, ‘i’, ‘o’, ‘u’ are termed as vowels. All other alphabets are called consonants.

Note: You have to only remove vowels from the string. There will be no change in the relative position of all other alphabets.

For example:

(i)  If the input string is 'CodeGeek', the output should be CdGk after removing ‘o’ and ‘e’.

(ii) If the input string is 'Odinson', the output should be 'dnsn' after removing ‘o’ and ‘i’.
