Here__Given an m x n 2D binary grid grid which represents a map of '1's (land) and '0's (water), return the number of islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. You may assume all four edges of the grid are all surrounded by water. Example 1: Input: grid = [ ["1","1","1","1","0"], ["1","1","0","1","0"], ["1","1","0","0","0"], ["0","0","0","0","0"] ] Output: 1 Example 2: Input: grid = [ ["1","1","0","0","0"], ["1","1","0","0","0"], ["0","0","1","0","0"], ["0","0","0","1","1"] ] Output: 3.
Consider the following page reference string 1, 2, 3, 4, 2, 1, 5, 6, 2, 1, 2, 3, 7, 6, 3, 2, 1, 2, 3, 6 How many page faults would occur for the following replacement algorithms, assuming one, two, three, or even four frames? Remember that all frames are initially empty, so your first unique pages will all cost one fault each.
Consider the bitmap representation of the free-space map, where for each block in the file, two bits are maintained in the bitmap. If the block is between 0 and 30 percent full the bits are 00, between 30 and 60 percent the bits are 01, between 60 and 90 percent the bits are 10, and above 90 percent the bits are 11. Such bitmaps can be kept in memory even for quite large files. Outline two benefits and one drawback to using two bits for a block, instead of one byte as described earlier in this chapter. Describe how to keep the bitmap up to date on record insertions and deletions. c .Outline the benefit of the bitmap technique over free lists in searching for free space and in updating free space information.

Suppose you have a finite state machine that accepts bit strings divisible by 11. The FSM has 11 states R0, R1, ... , R10, each corresponding to the remainder when dividing by 11. Input is fed to the FSM one bit at a time from left to right, the same way we did in our in-class examples. If the machine is currently in state R7, an input of 1 should transition it to which state? Type the subscript only of the new state. Your answer should be an integer between 0 and 10, inclusive.
Please help computer graphics question Let Z be the set of real integers and R the set of real numbers. The sampling process may be viewed as partitioning the x-y plane into a grid, with the central coordinates of each grid being from the Cartesian product Z2, that is a set of all ordered pairs (zi, zj), with zi and zj being integers from Z. Then, f(x, y) is a digital image if (x, y) are integers from Z2 and f is a function that assigns a gray-level value (that is, a real number from the set R) to each distinct coordinate pair (x, y). What happens to the digital image if the gray levels also are integers? a) The Digital image then becomes a 2-D function whose coordinates and amplitude values are integers b) The Digital image then becomes a 1-D function whose coordinates and amplitude values are integers c) The gray level can never be integer d) None of the mentioned

The key to cracking a substitution cipher was first discovered by Arab scholars in the ninth century, but it was not widely known in the West until the fifteenth century. Once frequency analysis of ciphers became widespread, the plain substitution cipher became useless. To fix the problems in the substitution cipher, Blaise de Vigenère invented the strategy of using multiple letter mappings. Rather than using one key for the whole message, Vigenère’s idea was to use a different key for each letter of the message. Using a different key for each letter makes the frequency analysis much more difficult. The key to the Vigenère cipher is the Vigenère square. The rows shown here are simple rotations of the alphabet. Each row in the table shifts the letters of the alphabet one place to the left. When a letter shifts out of the first . The idea is to have the message we want to encode: secretmessage Alongside a word we will use to encrypt: encryptencrypt Plaint text s e c r…
