Question
Search a sorted matrix: The input consists of a real number x and a matrix A[1..n, 1..m] of nm real values, where A[i, 1..m] and A[1..n, j] are the rows and columns, respectively, of the matrix. The objective is to either state that all of the members of A are greater than x or to locate the largest array entry A[i, j] that is less than or equal to x. Create and evaluate an iterative approach for this issue that looks at the least amount of matrix entries feasible. If you think the issue can be resolved with a straightforward binary search, think twice.

- Please implement the linear search algorithm on a randomly generated 23 member array. All numbers should be generated randomly and the expected SEARCH number also should be generated randomly.arrow_forward2. An interpolation search assumes that the data in an array is sorted and uniformly distributed.Whereas a binary search always looks at the middle item in an array, an interpolation searchlooks where the sought-for item is more likely to occur. For example, if you searched yourtelephone book for Victoria Appleseed, you probably would look near its beginning ratherthan its middle. And if you discovered many Appleseeds, you would look near the lastAppleseed. Instead of looking at the element a[mid] of an array a, as the binary search would,an interpolation search examines a[index], where p = (desiredElement - a[first]) / (a[last] - a[first]) index = first + [(last – first) × p]Implement an interpolation search of an array. For particular arrays, compare the outcomesof an interpolation search and of a binary search. Consider arrays that have uniformlydistributed entries and arrays that do not.

Each row records an employee's seven-day work hours with seven columns. For example, the following array stores the work hours for eight employees.

(Check for availability if name exist, no duplicate names) For each employee, enter the seven-day work hours and save them in a two dimensional array. Compute the total hours worked by each employee and save them in one dimensional array. Compute the wages of employees as follows: up to 40 hours per week the hour price is 20 otherwise the overtime hour price is 1.2 regular hour price.…arrow_forward
