[SOLVED] Why this doesn't generate a string as expected?

Question

I'm trying to generate a encryption key as mentioned in thr CryptoCube challenge, but the output isn't as expected instead it generates a very long integer. Can someone help me figure what I'm doing wrong?

I'm trying to generate something like this,

0:U:U:L:R,1:U,2:D:R,3:U:R

Answer 1

Line 25 is adding your 2 characters ':' and the map one together. Change ':' to ":" and you will get string concatenation.

Answer 2

Always use double quotes on characters to make them a string of one character, if you are using them in strings.

Answer 3

Thank you Mr. John Wells, I didn't know that would've been the problem.
