Answer:

def element_loc():

   is_end = 'n'

   dimen2 = []

   while is_end == 'n':

       par1 = input("Enter rows and columns: ").split(",")

       part = [int(i) for i in par1]

       dimen2. append(part)

       is_end = input("Do you want to add more rows? y/n: ")

   mini = list()

   for i in dimen2:

       mini. append(min(i))

   result = min(mini)

   row_index = mini. index(result)

   col_index = dimen2[row_index]. index(result)

   print("Row: ", row_index, "Col_index: ", col_index)

element_loc()

Explanation:

The python program solution above prompts users for the two-dimensional array and then the rows of the array are compared with the minimum value stored in another list or array. The row index and the column index are gotten from the mini and dimen2 arrays respectively and are displayed as the position of the minimum value in the two-dimensional array.

Select the correct statement(s) regarding partial mesh networks.
sweet [91]

Answer: all the answers are correct

Explanation:

Partial mesh networks is simply a packet switching networks which is connected and require that there should be establishment of a circuit before the exchange of packets.

Partial mesh networks are less expensive to implement when they're being compared to the full mesh networks and are also less redundant.

The correct statements regarding partial mesh networks are:

•the number of links connecting nodes in a partial mesh network depends upon the availability and reliability requirements of the network

• switches play an integral role in a partial mesh network, where several paths through the network are available

• redundant links and switches are used to improve the availability and reliability of partial mesh networks

The purpose of this assignment is to determine a set of test cases knowing only the function’s specifications, reported hereaf
Nesterboy [21]

Answer:

The program is written using PYTHON SCRIPT below;

N=int(input(" Enter number of Rows you want:"))

M=[] # this for storing the matrix

for i in range(N):

l=list(map(int,input("Enter the "+str(i+1)+" Row :").split()))

M.append(l)

print("The 2D Matrix is:\n")

for i in range(N):

print(end="\t")

print(M[i])

W=[] # to store the first non zero elemnt index

T=[] # to store that value is positive or negative

L=len(M[0])

for i in range(N):

for j in range(L):

if (M[i][j]==0):

continue

else:

W.append(j) # If the value is non zero append that postion to position list(W)

if(M[i][j]>0): #For checking it is positive or negative

T.append(+1)

else:

T.append(-1)

break

print()

print("The first Non Zero element List [W] : ",end="")

print(W)

print("Positive or Negative List [T] : ",end="")

print(T)

Explanation:

In order for the program to determine a set of test cases it takes in input of 2D matrix in an N numbet of rows.

It goes ahead to program and find the column index of the first non-zero value for each row in the matrix A, and also determines if that non-zero value is positive or negative. The If - Else conditions are met accordingly in running the program.

The difference between the centerline of a vehicle and the line perpendicular to the rear wheels is called what?
snow_lady [41]
The thrust angle is an imaginary line drawn perpendicular to the rear axle's centerline. It compares the direction that the rear axle is aimed with the centerline of the vehicle. It also confirms if the rear axle is parallel to its front axle and that the wheelbase on both sides of the vehicle is the same.
