regex - Redshift regular expression for domain extraction -

i have problems ajaxcontroltoolkit's colorpickerextender while using latest version of asp.net. (after doing little digging in development tools on chrome, found out it's padding.) whenever try use colorpicker, shows this: 8px padding want this: 0px padding i think bootstrap css automatically being applied padding of colorpicker table, automatically generated. my question is, how make sure keeps 0px padding? here's use in aspx file. <edititemtemplate> <tr style=""> <td> <asp:button id="updatebutton" runat="server" commandname="update" text="update" /> <asp:button id="cancelbutton" runat="server" commandname="cancel" text="cancel" /> </td> <td> <asp:textbox id="nametextbox" runat="server" text='<%# bind("name") %>' /> </td> <td>

java - PalindromeChecker comparTo -

i trying make palindrome (the inverse of word word self e.g. tacocat) checker in java. use code: private static void palindroomchecker(string sword){ char[] arrcword=sword.tochararray(); char[] arrcdrow=new char[arrcword.length]; for(int i=0;i<arrcword.length;i++) for(int j=arrcdrow.length-1;j>=0;j--) arrcdrow[j]=arrcword[i]; string sdrow=new string(arrcdrow); if(sword.compareto(sdrow)==0) system.out.println(sword); else system.out.println("false"); } for reason keep printing false. reason there no palindrome's not tacocat. you need index. should work. private static void palindroomchecker(string sword) { char[] arrcword = sword.tochararray(); char[] arrcdrow = new char[arrcword.length]; int = 0; (int j = arrcdrow.length - 1; j >= 0; j--) arrcdrow[j] = arrcword[i++]; string sdrow = new string(arrcdrow); if (sword.compareto(sdrow) == 0) system
