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.
