Ji also see another problem
Jwait no
Jright here will it change the value of things.count while it's going thru the loop
Jor does it only take in a value when first going into the loop
Phover over the read squiggle, what does it say? 
J
Jnot sure how to make it an int on declaration tho
Pthere you go
Ji make it an int inside the loop so idk what to do
Pyou don't capture the int you throw it away
MWhat is the intent of using a random here?
Jshuffle the things
MPick a random item from things?
Jyes
Mthings[random.Next(0, things.Length)]MYou need to use random to produce an int in the range that you want.
MYou do that by calling the Next method on random.
Ji did it like this but now it's only returning 2 of the 3 options
J
MSo, things.Count is changing as your loop runs.
MThat's a problem.
Ji see
Jbut i don't want the same string to be duplicated so i'm removing it from the original list
Jif i don't change the random max then it has a chance to land on an index that doesn't exist in the list
MHow do you think you might solve this?
MHint: try using a different kind of loop.
J
Jit's messing up because i'm messing with the things list during the loop
MYeah you can't modify something you are using foreach over.
Jhm
Ouse
for.Ji was
Jand it wasn't working
MLet's describe the algorithm in plain english and you can translate it to code:
To shuffle the list:
while the list of things is non-empty, pick a random number between 0 and how many things the list contains. Add the item at that index in things to the end of the result list. Now remove it from things.

OIt looks like Fisher-Yates.
Jyes
MThis isn't Fisher Yates
MFisher Yates is in-place.
Jin this statement does it take the value of things only at the beginning
Jor does it keep updating each time it goes through the loop
MIt keeps updating.
MThat's the problem.
Johhhhh
Ji got it now
Jtysm!!
MI was actually suggesting this:
MJohhhhhhhhhhh
Ji never used a while loop before
Jonly do while
