existence is set to 1, otherwise set to 0, then all less than rk[i] The element is x[rk[i]-1]+x[rk[i]-2]+...+x[2]+x[1]. And that's one of the classic uses of bit--to ask for prefixes and! since it is scanned from the back, it is definitely the element on the right of I that is marked! The x array is introduced here just for ease of understanding, in fact only the S array is used to count the and of each no

, so the is not a valid solution. In the second sample case: On the first level, ZS the coder pressed the ' + ' button 999999999999999998 times (and the number on screen is initially 2), so the number became 2 + 999999999999999998 1 = 1018. Then, ZS the coder pressed the "button, and the number became. After then, on the second level, ZS pressed the ' + ' button 44500000000 times, so the number becomes 109

C: first judge whether it is a multiple of 3, and then pre-process the prefix, position, suffix, and number of corresponding sum/3. Then, scan the current one from the beginning to the end and combine it with the next one. D: pre-process the busines

estimated that browsers earlier than IE6 cannot correctly parse the CSS file because of the encoding problem, so CSS does not work in IE6. There are still many people in IE6. Therefore, this problem must be solved: Method 1: the CSS, JS and web files are stored in a unified UTF-8 format. Method 2: Remove Chinese comments in CSS and JS, or change them to English. The preceding section shows that the CSS file cannot be correctly parsed due to encoding
