. Instead He gave you an array a1, A2, ..., Aksuch that
In other words, n was multiplication of all elements of the given array.
Because of precision difficulties, Barney asked you to tell him the answer as an irreducible fraction. In all words need to find it as a fraction p/q such that, where is the greatest common divisor. Since p and Q can be extremely large, you have need to find the remainders of dividing each of the them by 109 + 7.
Please note that we want the P and Q to is 1, not the th
Overview
We know that the Silverlight 2 provides a rich network communication API, including support for SOAP services, rest services, HTTP based communications, socket communications, and more. In this article, I'll show you how to apply a Web service to file uploads and e-mail messages in Silverlight 2 with a few examples.
Uploading files using Web service

ical ordering in the output when considered as a string. If The task is impossible, print one line with the word "impossible".
Input Line 1:two space-separated integers:m and NLines 2.. M+1:line i+1 describes the colors of the row I of the grid with N space-separated integers which is 1 for BL ACK and 0 for White
Output Lines 1.. M:each line contains N space-separated integers, each specifying what many times to flip this particular location.

A label file is one of the JSP custom tags that is implemented by creating a. tag file, such as Table.tag, in the Web-inf\tags directory or subdirectory, and using the Taglib directive to refer to the directory in which the. tag file resides, as follows:
If you use the Struts 2 tag in a tag file, you can create a problem. Let's look at an example.
Create a Table.tag file in the Web-inf\tags directory with the following code:
