quadraticequation.py 这个程序的名称为 quadratic equation 组合,是二次方程的英文词组。 这个程序用来求解二次方程式: #!/usr/bin/env python3 import math a = int(input("Enter value of a: ")) b = int(input("Enter value of b: "))
There always two solutions to a quadratic equation: x_1 & x_2. """ x_1 = (- b+(b**2-4*a*c)**(1/2)) / (2*a) x_2 = (- b-(b**2-4*a*c)**(1/2)) / (2*a) return x_1, x_2 对于单行文档字符串,请将 """ 保留在同一行: ...

O(n2) quadratic The runtime is a quadratic function of the size of the input. A naive implementation of finding duplicate values in a list, in which each item has to be checked twice, is an example of a quadratic algorithm. O(2n) exponential The runtime grows exponentially with the size...
