The problem with removing commas is that the input string might have some numbers inside it whether the comma is used as a decimal point (common in continental european number formatting, whereas the UK and US use a period for that). This is very nasty, and wikipedia [[wp:Decimal mark|goes to some length]] on the subject's background. I recommend dropping that part of the task (though removing spaces between digit sequences ''is'' fine; it's not ambiguous except in situations which aren't polynomials at all). –[[User:Dkf|Donal Fellows]] 21:16, 14 January 2012 (UTC) |

: That is not strictly true, though it could well be true for the definition of this task: J will represent polynomials as a space separated list of numeric coefficients (with constant being the first number). --[[User:Rdm|Rdm]] 23:44, 14 January 2012 (UTC) |
