RSS订阅原创 L1-032 Left-pad (20 分)
L1-032 Left-pad (20 分)根据新浪微博上的消息，有一位开发者不满NPM（Node Package Manager）的做法，收回了自己的开源代码，其中包括一个叫left-pad的模块，就是这个模块把javascript里面的React/Babel干瘫痪了。这是个什么样的模块？就是在字符串前填充一些东西到一定的长度。例如用*去填充字符串GPLT，使之长度为10，调用left-pad的结果就应该是******GPLT。Node社区曾经对left-pad紧急发布了一个替代，被严重吐槽。下面就请

原创 L1-011 A-B (20 分)
L1-011 A-B (20 分)本题要求你计算A−B。不过麻烦的是，A和B都是字符串 —— 即从字符串A中把字符串B所包含的字符全删掉，剩下的字符组成的就是字符串A−B。输入格式：输入在2行中先后给出字符串A和B。两字符串的长度都不超过104，并且保证每个字符串都是由可见的ASCII码和空白字符组成，最后以换行符结束。输出格式：在一行中打印出A−B的结果字符串。输入样例：I love GPLT! It's a fun game!aeiou输出样例：I lv

原创 L1-009 N个数求和
L1-009 N个数求和 (20 分)本题的要求很简单，就是求N个数字的和。麻烦的是，这些数字是以有理数分子/分母的形式给出的，你输出的和也必须是有理数的形式。输入格式：输入第一行给出一个正整数N（≤100）。随后一行按格式a1/b1 a2/b2 ...给出N个有理数。题目保证所有分子和分母都在长整型范围内。另外，负数的符号一定出现在分子前面。输出格式：输出上述数字和的最简形式 —— 即将结果写成整数部分 分数部分，其中分数部分写成分子/分母，要求分子小于分母，且它们没有公因子。如果结果
