由 ぃ、小莉子 提交于 2019-12-12 05:49:25
问题 So I'm trying to find the longest repeat for a specific pattern thats given. My code so far looks like this, and is fairly close, however it does not fully give the wanted result: use warnings; use strict; my $DNA; $DNA = "ATATCCCACTGTAGATAGATAGAATATATATATATCCCAGCT" ; print "$DNA\n" ; print "The longest AT repeat is " . longestRepeat($DNA, "AT") . "\n" ; print "The longest TAGA repeat is " . longestRepeat($DNA, "TAGA") . "\n" ; print "The longest C repeat is " . longestRepeat($DNA, "C") . "\n

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 现在经常会遇到让输入身份证号码的需求，那么我们应该如何验证身份证号码的合法性呢？今天我们来说一说验证的方法。 function checkIdcard(num){ num = num.toUpperCase(); //身份证号码为15位或者18位，15位时全为数字，18位前17位为数字，最后一位是校验位，可能为数字或字符X。 if (!(/(^\d{15}$)|(^\d{17}([0-9]|X)$)/.test(num))) { alert('输入的身份证号长度不对，或者号码不符合规定！\n15位号码应全为数字，18位号码末位可以为数字或X。'); return false; } //校验位按照ISO 7064:1983.MOD 11-2的规定生成，X可以认为是数字10。 //下面分别分析出生日期和校验位 var len, re; len = num.length; if (len == 15) { re = new RegExp(/^(\d{6})(\d{2})(\d{2})(\d{2})(\d{3})$/); var arrSplit = num.match(re); //检查生日日期是否正确 var dtmBirth = new Date('19' + arrSplit[2] + '/' +

Select without duplicate from a specific string/key

由 会有一股神秘感。 提交于 2019-12-11 16:48:50
问题 Thanks to @Ed Gibbs i managed to solve my first problem on this case (Select duplicate and keep the oldest (not based on ID)) I am now facing a new problem I can not solve. I have two tables, "domain" which is clear of duplicate and "email" which contains duplicate. In the first table i had a value called "creationdate" which i used as a filter. In the second table i don't have any filter but some informations could (i think) be used to act as a filter. Table domain : | domain | value 1 |

问题 I'm writing a program that generates star wars names. The user inputs their first, last, mother's maiden name, birth city, and first car and the program gives a star wars name. I need the last two characters* of the user inputted last name. I know I can use substring , but I cannot get anything to work. The best I have is: lastname.substring(lastname.length() -2) which gives the first two letters of the last name, and not the last. Also, I cannot use lastname.substr(-2) because substr for
