Suppose that we wish to compress this picture slightly. Specifically, we wish to remove one pixel from each of the m rows, so that the whole picture becomes one pixel narrower. To avoid disturbing visual effects, however, we require that the pixels removed in two adjacent rows be in the same or adjacent columns; the pixels removed form a “seam” from the top row to the bottom row where successive pixels in the seam are adjacent vertically or diagonally. a. Show that the number of such possible seams grows at least exponentially in m, assuming that n > 1. b. Suppose now that along with each pixel A[i, j], we have calculated a real-valued disruption measure d[i, j], indicating how disruptive it would be to remove pixel A[i, j]. Intuitively, the lower a pixel’s disruption measure, the more similar the pixel is to its neighbors. Suppose further that we define the disruption measure of a seam to be the sum of the disruption measures of its pixels. Give an algorithm to find a seam with the lowest disruption measure.

COMPUTER SCIENCE A non-governmental organization needs a program to calculate the amount of financial assistance for needy families. The formula is as follows: - If the annual household income is between $30,000 and$40,000 and the household has at least three children, the amount is $1,000 per child. If the annual household income is between$20,000 and $30,000 and the household has at least two children, the amount is$1,500 per child. - If the annual household income is less than $20,000, the amount is$2,000 per child. Implement a function for this computation. Write a program that asks for the household income and number of children for each applicant, printing the amount returned by your function. Use –1 as a sentinel value for the input. Verified answer Recommended textbook solutions

What describes the superblock's function in the Linux file system?The superblock essentially records a file system's characteristics – block size, other block properties, sizes of block groups and location of inode tables. The superblock is especially useful in UNIX and similar operating systems where a root directory contains a variety of subdirectories.
Which of the following is the home directory for the superuser?The Unix superuser has access to all directories on the filesystem, and hence can access home directories of all users. The superuser's home directory on older systems was /, but on many newer systems it is located at /root (Linux, BSD), or /var/root (Mac OS X).
