1 and 0 occurrences of the place, 1 and 0 appear two times, since there is no 0, then 1 is occupy the first and second position (please read this sentence carefully, this sentence read, the whole algorithm understand). Then we put one of the 1 in the position of the second position of the 1 b[1], while c[1]-1, because we have already lined up a 1.Next, I=1,a[1]=2,c[2] is less than or equal to 2 of the number of occurrences, c[2]=4, then to rank it in fourth place, that is b[3] position, while c

Stacks and queuesStack (last in, first out)Stack, which allows access to only one data item: The last inserted data item.Stacks can be used to check the matching problems of parentheses and parse mathematical expressions, similar to those used in the compilation principle.The operation of the picture is actually summed up: 1. Read the left delimiter into the stack, 2. The right delimiter is read to match th
) + (N-2) +...+1 = N (N-1)/2When the value of N is very large, the algorithm compares the number of N2/2 times, ignoring minus 1.Assuming that the data is random, it is possible to swap locations each time, possibly without swapping, assuming a probability of 50%, then the number of interchanges is N2/4. However, if the worst-case scenario is that the initial data is reversed, the position is swapped for ea

The pointer on the left, Leftptr, moves to the right, while the pointer on the right, rightptr, moves to the left.In fact, leftptr initialization is at the left of the first data item, and Rightptr is on the right-hand side of the last

of red-Haishi. But they can't all be full, so the height of the 2-3-4 tree is roughly log2 (n+1) and log2 (n+1)/2. Reducing the height of the 2-3-4 tree makes it shorter to find than red-Haishi.On the other hand, each node has more data items to view, which increases the lookup time. Because a linear search is used in a node to view data items, the multiple of the lookup time is proportional to M, which is
