Write a program that asks user to input an index first, then asks the user to enter words and constructs a list of characters in each word under the index. If a word does not have the character under the given index then it will be skipped. The program must work exactly like the following example.

For example:

Enter a word $($or type Q to quit$)$: xyztw

Enter a word $($or type Q to quit$)$: abcdef

Enter a word $($or type Q to quit$)$: blah

Enter a word $($or type Q to quit$)$: Q

List of characters:

$[\text{'}$t$\text{'},\text{'}$t$\text{'},\text{'}$d$\text{'},\text{'}$h$\text{'}]$
