( 10627 ) C Simple Strings PROGRAMMING dp greedy strings 1200

B"zscoder loves simple strings! A string t is called simple if every pair of adjacent characters are distinct. For example ab, aba, zscoder are simple whereas aa, add are not simple. zscoder is given a string s. He wants to change a minimum number of characters so that the string s becomes simple. Help him with this task! The only line contains the string s (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89|s| xe2 x80 x89 xe2 x89 xa4 xe2 x80 x892 xc2 xb7105) -- the string given to zscoder. The string s consists of only lowercase English letters. Print the simple string s' -- the string s after the minimal number of changes. If there are multiple solutions, you may output any of them. Note that the string s' should also consist of only lowercase English letters. "...
