Level $2($weight: $75\%)$

Once the basic function haveSameLetters has been completed, you can use it to accomplish the

task for Level $2.$ To run Level $2,$ you simply have to pass in something other than $1$ you could pass in

$2,$ or you could simply pass in no command$-$line argument at all.

When the command line argument is not $1,$ the code in main$()$ branches off to the else block.

This is where you need to place your code for Level $2.$ We have already provided the first part: words

are read in from standard input, and they are stored one by one inside a vector $($we are using the

Standard Template Library vector class for C$++).$ In the next part of the code, you need to access

the words inside the vector, and print out all groups of words that have exactly the same letters.

Groups of words should be separated by commas $($no spaces$),$ and each group should appear on a

new line.

For example, if our input is

sore cake rose leaf teal fear late

Then the output should be

sore,rose

teal,late

$($words should appear in the order in which they were entered into the vector.$)$

If the input is

earth heart hater atom moat mother

then the output should be

earth,heart,hater

atom,moat

Note that there are several tests in Level $2,$ and it carries mor
