Web1) you do not need a segment tree, you can use binary search + sparse table 2) the log factor is a logn, which is around 13, so its about 2.5 * 10^8 complexity, not unreasonable 3) my recursive segment tree runs in 4s which is only twice the TL. If i could write iterative segmemt tree, i am pretty sure it would pass. Web17 okt. 2024 · You can combine two loops into one and cast innerList out: evnSum = oddSum = m = 0; for (int j = 0; j < N - 1; j++, m++) { int temp = (int) (1 << j); if ( (i & temp) > 0) { if (m%2==0) evnSum += arr [j]; else oddSum += arr [j] } } But, of course, you'll be unable to output evnSum before the whole innerList this way.

WebThe total number of nodes and edges is O(n) due to the observations. Basically, we always have that c(10) + c(00) and c(01) + c(11) are fixed because the string b doesn't change, and after an even number of operations we also have c(10) + c(11) is fixed because two operations is just a swap. From these three equations, the count c(10) uniquely ... WebCodeforces.
