In Problem D of yesterday's contest, I'm getting WA on test case 3. The checker log says "wrong output format Unexpected end of file — int32 expected", This is an interactive problem and I'm not really able to understand the meaning of the verdict. My logic is correct but if someone wants to have a look at the code here is the submission link: 119374235 .

Problem: Problem E (CF Round 675 Div 2) The verdict says: wrong answer 141st lines differ — expected: '430 hhccc...io', found: '428 ccccc...io'

If we remove "hh", won't 'ccccc...io' become lexicographical smaller than 'hhccc...io'?
