Given a pair of positive integers, for example, 6 and 110, can this equation 6 = 110 be true? The answer is yes, if 6 is a decimal number and 110 is a binary number. Now for any pair of positive integers N​1​​ and N​2​​, your task is to find the radi…

Given a pair of positive integers, for example, 6 and 110, can this equation 6 = 110 be true? The answer is "yes", if 6 is a decimal number and 110 is a binary number. Now for any pair of positive integers N1 and N2, your task is to find the rad…

一.技术总结 首先得写一个进制转换函数convert(),函数输入参数是字符串str和需要转化的进制(使用long long数据类型).函数内部知识,使用函数迭代器,即auto it = n.rbegin(),这里it作用就是指针一样,装的是地址,了解函数begin()是返回字符串str的一个元素地址和函数end()是返回字符串最后一个元素还要往后一位,而rbegin()和rend(),加了r后刚刚反过来了,rbegin()指向str的最后一个元素,rend()指向第一个元素还要往前一位. 第二…
