The following is an example of three fields in cube:

data columns are affected by the update operation. The result of this field is varbinary (4100 ). This field returns a valid value only when the TRACK_COLUMN_UPDATED option is set to ON when Change Tracking is activated ON the table, and is NULL for the INSERT and DELETE operations, because DELETE and INSERT actually affect all data columns, only the UPDATE operation will return the value. The value of this field can be parsed using the CHANGE_TRACKI

Unfortunately, Vasya can only sum pairs of Integers (A,B), Such that for any decimal place at least one number has digit 0 in this place. For example, Vasya can sum numbers 505 and 50, but he cannot sum 1 and 4.
Vasya has a setKDistinct non-negative integersD1,D2 ,...,DK.
Vasya wants to choose some integers from this set so that he cocould sum any two chosen numbers. What

Kitahara Haruki has boughtNApples for Touma Kazusa and Ogiso Setsuna. Now he wants to divide all the apples between the friends.
Each apple weights 100 grams or 200 grams. of course Kitahara Haruki doesn't want to offend any of his friend. therefore the total weight of the apples given to Touma Kazusa must be equal to the total weight of the apples given to Ogiso Setsuna.
But unfortunately Kitahara Haruki doesn't have a knife right now, so he cannot split any apple into some parts. please, tell

For example, if the system is Microsoft Windows, you can directly select the TCP/IP protocol, if there is a Netware system, you also need to configure the Novell IPX/SPX protocol. Their selection is the same as the NIC communication protocol. Note that the default printer configuration enables all communication protocols at the same time. Do not dis
