Some cryptographic algorithm requires matching natural numbers that can be represented as a sum of t...: ответ на тест 1054945 - Информатика

Some  cryptographic algorithm requires matching natural numbers that can be represented as a sum of two different prime numbers using more than k ways, thus all the three numbers (the unknown and two summands) should have the same number of digits. For example: number 30 matches k-1 case as it can be represented as follows:  and . Number 32 doesn’t match as it can be represented by only one sum: 19+13.
The quantity of 4-digit  decimals for k= 10 is …

The sequence of natural numbers  from  to  is represented without any spaces between them. The decimal sequence obtained is sorted descending the one-digit numbers corresponding to the decimals. For example for   and  the ordered sequence will have the following representation:
98765211110. For  and  the sequence will contain as many “7” digits as____, the first of which is in position with ordinal number _____.
Give your answer in two numbers separated by a comma. For example for  and  in the sequence there will be 19 digits of 7 beginning from position number 39. Thus the result is written as 19,39

The number 75110 in the radix number system with q-base is represented as follows: 11100110011q the base of this system will be the following …

It’s common knowledge that if the 13th of a month is a Friday you should be very careful or even better put off all your affairs and keep your head down. Just in case. You should be especially careful to do so if the Friday of the 13th occurs in the leap year. The horror of the horror is when Friday of the 13th happens in February of the leap year.
From the beginning of A.D. such Horror of the Horror days (Friday of the 13th in February of the leap year) there were as many as …
When calculating use the Gregorian Style. The last Friday the 13th was on 13 July, 2012.

Little Piggy decided to categorize his archive containing a lot of different format files. There are pictures, videos, audio, documents, e-tables, documents templates. Web-pages with different file extensions, text of programs in different programming languages and even unknown content files with .hrj extension. Altogether there are 1001111 files. At first Little Piggy decided to move all the pictures into one folder. Thus he selected 5 filtering masks for file names. Most files will be filtered when using the following mask …
Let’s presume that the number of files of every format is relatively similar.

A programmer wrote a program in machine language. Every instruction represents a 32-bit digit. The program requires 1DDh bites of memory. The address of the last instruction is A00h. The program is allocated in memory beginning with the following address …
