evaluate

问题 Suppose the user inputs an infix expression as a string? What could be the easiest ( By easiest I mean the shortes t) way to evaluate the result of that expression using C language? Probable ways are converting it to a postfix then by using stacks.But its rather a long process. Is there any way of using functions such as atoi() or eval() that could make the job easier? 回答1: Certainly the most instructive way (and possibly even the easiest, once you know how) is to learn how to write your own

问题 I want to add a keyboard shortcut for the command 'Debug: evaluate' in Visual Studio Code. Unfortunately, the command ID for the command 'Debug: evaluate' is not documented. Did someone know where to find the commandId ? 回答1: editor.debug.action.selectionToRepl is what you are looking for. It will execute the current selected text in the debugger console. https://github.com/Microsoft/vscode/blob/d2b6bbb46fbdf535e2c96b3e00ac56ac1d427a69/src/vs/workbench/parts/debug/browser/debugEditorActions

问题 I have these problems about polynomials and I've spent about 4 hours on this, but I just can't get it. I'm new to Python and programming and I've tried working it out on paper, but I just don't know. Write and test a Python function negate(p) that negates the polynomial represented by the list of its coeffeicients p and returns a new polynomial (represented as a list). In other words, write a function that makes the list of numbers negative. Write a Python function eval_polynomial(p, x) that

问题 I read several old posts about Google Spreadsheet missing the evaluate function. There is any solution in 2016? The easiest example. 'A1' contains the following string: UNIQUE(C1:C5) 'B1' I want to evaluate in it the unique formula written in 'A1'. I've tried concatenating in this way: 'B1' containing ="="&A1 but the outcome is the string =UNIQUE(C1:C5). I've also tried the indirect formula. Any suggestion to break last hopes, please? Additional note The aim is to write formulas in a
