If there can be several solutions to that problem, print the lexicographically minimum one. I.e. the solution where the first line is less than the first line of other solutions should be printed. If the two lines are equal, compare the second lines and so on. The lexicographical comparison...
You’re given a string s which consists of 27 upper-case English letters. Each English letter occurs at least once in s. Find a grid that contains a path whose tiles, viewed in the order that the path visits them, form the string s. If there’s no solution, print “Impossible” (wi...

Now, ZS the Coder tells you a word, where some of its letters are missing as he forgot them. He wants to determine if it is possible to fill in the missing letters so that the resulting word is nice. If it is possible, he needs you to find an example of such a word as well. ...
Each puzzle solution in the input starts with a line containing two integers r and c (1 <= r <= 10 and 1 <= c <= 10), where r (the first number) is the number of rows in the puzzle and c (the second number) is the number of columns. The r rows of input which follow eac...
The subsequence of stringais a stringbthat can be derived from the stringaby removing some symbols from it (maybe none or all of them). In particular any string is the subsequence of itself. For example, the string "cfo" is the subsequence of the string "codeforces". ...
