oddSum += num print(oddSum) 本题编程思路如下:首先,需要读取输入的两个整数m和n,其中n应该小于m,可以使用input函数获取输入;定义一个变量oddSum,初始值为0,用于存储奇数之和;使用一个循环遍历从m到n之间的所有数字;在循环中,使用条件判断语句判断当前数字是否为奇数,如果是奇数,将其加到oddSum中;循环结...
In the first test case, you can represent3as3. In the second test case, the only way to represent4is1+3. In the third test case, you cannot represent10as the sum of three distinct positive odd integers. In the fourth test case, you can represent10as3+7, for example. In the fifth...
(2)方法名为oddSum,输入一个整数n,求1到n的奇数和。要求:如果n小于0,输出“您输入的是负数!”,不必求和,否则计算结果并输出。(3)方法名为equationRoot,输入任意三个整数 a、b、c,求 一元二次方程的根。要求: 如果判别式小于0,输出“此方程式没有实根!” ,不必求根。 如果判别式等于0,输出“此方程式...
Given a positive integerN, how many ways can we write it as a sum of consecutive positive integers? Example 1: Input: 5 Output: 2 Explanation: 5 = 5 = 2 + 3 Example 2: Input: 9 Output: 3 Explanation: 9 = 9 = 4 + 5 = 2 + 3 + 4 ...
