SAP 2020 new grad

投的职位是 SAP next rotation Jan 2020
Next Talent Rotational Program

第一题: 给一段代码,问如何优化, 类似 meeting room,找匹配的lunch时间
第二题: 333 input is n, return pattern
313
323
333
第三题 还是 prime number那道题,input is n and a list of number, return String
eg. (80, 4819 4087 4757)
should return EBCD
because 4819 = 79 * 61 = E * B
4087 = 61 * 67 = B * C
4757 = 67 * 71 = C * D

做完一直没消息。。
