The task was very simple - given an arithmetic expression, return the result of evaluating this expression. However, looks like there is a bug in the reference solution...InputThe only line of input data contains the arithmetic expression. The expression will contain between 2 and 10 operands, separated with arithmetic signs plus and/or minus. Each operand will be an integer between 0 and 255, inclusive.OutputReproduce the output of the reference solution, including the bug.ExamplesInput8-7+6-5+4-3+2-1-0Output4Input2+2Output-46Input112-37Output375
