The algorithm of converting a certain  sequence of symbols is set. At every stage of the algorithm the following operations are carried out:
1) at the end of the sequence before stepping its copy in the reversed order is written (symbols are written in the reversed order);
2) at the end of the sequence obtained the quantity of symbols that equals the stepping number of the algorithm is removed.
The results of the first two steps are given for 1234 input sequence:
1: 1234432
2: 123443223443
As for the input sequence of ALGORITM symbols after the 10th step of transformation there will be symbol _____ on position 1024.

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
