( 9324 ) B Polycarp and Letters PROGRAMMING brute force implementation strings 1100

B"Polycarp loves lowercase letters and dislikes uppercase ones. Once he got a string s consisting only of lowercase and uppercase Latin letters. Let A be a set of positions in the string. Let's call it pretty if following conditions are met: Write a program that will determine the maximum number of elements in a pretty set of positions. The first line contains a single integer n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89200) -- length of string s. The second line contains a string s consisting of lowercase and uppercase Latin letters. Print maximum number of elements in pretty set of positions for string s. In the first example the desired positions might be 6 and 8 or 7 and 8. Positions 6 and 7 contain letters 'a', position 8 contains letter 'b'. The pair of positions 1 and 8 is not suitable because there is an uppercase letter 'B' between these position. In the second example desired positions can be 7, 8 and 11. There are other ways to choose pretty set consisting of three elements. In the third example the given string s does not contain any lowercase letters, so the answer is 0. "...
