https://www.hackerrank.com/contests/101hack45/challenges/polynomial-division 询问一个多项式能否整除一个一次函数.a * x + b 注意到如果能整除,就比如是x^2 + 2 * x + 1能整除2 * x + 2 那么它必定能整除2 * x + 2的根,也就是和根肯定有交点. 因为你能整除,也就是(x^2 + 2 * x + 1) = k * (2 * x + 2) 那么k * (2 * x + 2)还是条直线.唯独使…

1 Fundamentals A polynomial is either zero, or can be written as the sum of one or more non-zero terms. The number of terms is finite. A term consist of a constant coefficient and a monomial, that is, the product of zero or more variables. Each varia…
https://en.wikipedia.org/wiki/Time_complexity#Polynomial_time An algorithm is said to be of polynomial time if its running time is upper bounded by a polynomial expression in the size of the input for the algorithm, i.e., T(n) = O(nk) for some consta…

Equations are given in the format A / B = k, where A and B are variables represented as strings, and k is a real number (floating point number). Given some queries, return the answers. If the answer does not exist, return -1.0. Example:Given a / b =…
Did you ever have the feeling that adding people doesn't help in software development? Did you ever think about the reason? And do you have any idea to make a change? Traditional software engineering emphasizes on division of work by modules, values…

Description 题目描述 You are given an polynomial of x consisting of only addition marks, multiplication marks, brackets, single digit numbers, and of course the letter x. For example, a valid polynomial would be: (1+x)*(1+x*x+x+5)+1*x*x. You are required…
IMO, version 1 better than version 2, version 2 better than version 3. make some preprocess to make you code simple and efficient. Here divide the input by 2, so you don't have to do dividsion on each loop. version 1 is best thanks to http://www.cnbl…

Optimum polynomial If we are presented with the first k terms of a sequence it is impossible to say with certainty the value of the next term, as there are infinitely many polynomial functions that can model the sequence. As an example, let us consid…
