Hi, let's isolate the issue. The problem is not in your editor or CW, the assert.deepEquals method or the input length. Your code solves a different problem :)

Look at the following case:

var input = "233312"
yourSolution(input) === [ [ '3', 3 ], [ '2', 2 ], [ '1', 1 ] ]
expectedResult      === [ [ '2', 2 ], [ '3', 3 ], [ '1', 1 ] ]

Hint: The description says: "return it as a list of tuples in order of appearance."

How does your editor know the correct answer?

if you carefully examine the random test error messages you can figure out how to correct your output based on the directions
