Scientific notation is the way that scientists easily handle very large numbers or very small numbers. The notation matches the regular expression [+-][1-9].[0-9]+E[+-][0-9]+ which means that the integer portion has exactly one digit, there is at lea…

科学计数法是科学家用来表示很大或很小的数字的一种方便的方法,其满足正则表达式 [+-][1-9].[0-9]+E[+-][0-9]+,即数字的整数部分只有 1 位,小数部分至少有 1 位,该数字及其指数部分的正负号即使对正数也必定明确给出. 现以科学计数法的格式给出实数 A,请编写程序按普通数字表示法输出 A,并保证所有有效位都被保留. 输入格式: 每个输入包含 1 个测试用例,即一个以科学计数法表示的实数 A.该数字的存储长度不超过 9999 字节,且其指数的绝对值不超过 9999. 输出格式…

In July 2004, Google posted on a giant billboard along Highway 101 in Silicon Valley (shown in the picture below) for recruitment. The content is super-simple, a URL consisting of the first 10-digit prime found in consecutive digits of the natural co…

Shuffling is a procedure used to randomize a deck of playing cards. Because standard shuffling techniques are seen as weak, and in order to avoid "inside jobs" where employees collaborate with gamblers by performing inadequate shuffles, many cas…
