再后 , 执行 init 初始化块 , 其中先执行 nameFirstLetter 函数 , 在该函数中调用了 fun nameFirstLetter() = name[0] 中的 name 属性 ,..., 但是在初始化之前调用了该 成员属性 , 编译时没有报错信息 , 但是运行时会报异常 ; 三、解决方案 --- 调换 初始化代码块 中的代码顺序 , 先给 name 成...
In number theory, Euler's totient function counts the positive integers up to a given integer n that are relatively prime to n. It is written using the Greek letter phi as φ(n) or ϕ(n), and may also be called Euler's phi function. Write a Python program to calculate Euclid's t...

Ultimately, there is no clearly defined predecessor to a floating-point number, so it is not an ordinal value. Whole numbers are ordinal numbers. Simple types such as Char and Boolean are also ordinal numbers. For instance, the letter B is succeeded by the letter C and preceded by the ...
s[i]only contains digits letters ('0'-'9') and'#'letter. swill be valid string such that mapping is always possible. 思路:判断一个数字字符应该转为a−ja−j的字符还是应该和后一位数字字符结合转为j−zj−z,应该看第三位字符,如果是##,则需要将其和后一位字符结合。
