aptitude are from number series and mixtures,
C,C++ are from pointers
Java from Threads,
In programming round they asked,
Program to print matrix in spiral form,
Program to reverse vowels alone in a given string
program to push all zeros to right side in an array and order should be maintained
program to print name in a list like below
if list contains 10-20 strings and if input is like c*i o/p should print all string in a list contains words starting with 'c' and ending with 'i'
eg:
list = [chennai, covai, madurai, delhi, dubai, mumbai]
then if i/p = c*i o/p-- chennai, covai
if i/p = d*i o/p --- dubai, delhi

Program to reverse vowels alone in a given string
====================================================

Given a string, your task is to reverse only the vowels of string.

Examples:

Input : hello
Output : holle

Input : hello world
Output : hollo werld
