请帮我看一下这两个方法怎么写?
1、
我传入一串数字做参数,返回这串数字的英文写法(纯英文)
例如,传12,返回twelve
传3000,返回three thousand
传50000,返回fifty thousand
传6000000,返回sisty million
传1234567890,返回one billion two hundred and thirty four million five hundred and sisty seven thousand2、
我传入一串数字做参数,返回这串数字的英文写法(数字+英文)
传3000,返回3 thousand
传50000,返回50 thousand
传6000000,返回6 million
传1234567890,返回1 billion 234 million 567 thousand谢谢!
