# **DAILY CHALLENGE**: Write a code that get as input a mathematical function as string. calculate and print the result of it!

RESTRICTIONS: 1) function is allways polynom of 2nd degree 2) each coefficient is included even if they are 0 3) + AND - can occure 4) allways exactly 6 whitespaces in the string (function) EXAMPLE 1: - input = "f(3) = 2x^2 + 1x - 2" - output = 19 EXAMPLE 2: input = "f(2) = 4x^2 - 2x + 0" output = 12 EXAMPLE 3: input = "f(5) = 0x^2 - 0x - 3" output = -3 PS: try to make your own parse function (if you're able to handle it) GOOD LUCK EVERYONE ... ENJOY CODING :)

Here's my python solution. I assumed first term couldn't be negative because it says always 6 white spaces. It returns floats because I wanted it to handle float without rounding. https://code.sololearn.com/cFH4q6S8N84g/?ref=app

ADDITIONAL EXPLANATION: - 6 whitespaces means (whitespace marked as underscore): f(3)_=_2x^2_+_1x_-_2 - input pattern is: ( - / + can change) f(X) = Ax^2 + Bx - C - not allowed input is: f(2) = 4x^2 - 2x -> missing C f(5) = - 3 -> missing Ax^2 and Bx f(3) = 1x -> missing Ax^2 and C

Got it! This was a fun one! You can use any positive number and 0 as x and any positive numbers and 0 as constants. Used a regex to get the pattern of the function. https://code.sololearn.com/cOc2G4zKd89P/?ref=app

Dear downvoters; with all due respect, if you found a bug in my code you could at least point it out. I'm sure that's a much more noble way to go about it don't you think?

So f(0) = 0x^0 + 0x + 0 works as an input?

@J G. f(0) = 0x^0 + 0x + 0 isn't a function of 2nd degree! it should be: f(0) = 0x^2 + 0x + 0 !!!
