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.
When it comes to front end, back end and full stack developer, the difference is determined by :
front end (the visible parts of a website)
back end (the “under the hood” databases and infrastructure)
full stack (a hybrid of both)
And front end developers work on technologies that are used to build front end(which is what clients visiting that website see)of application like HTML,CSS, Javascript ( Node js, Angular are also now used ).
Similarly back end developers work on back end technologies like Node js.
Full stack developers work on both front end and back end developers and know both end technologies as well.
For example :
MEAN Stack developer where
M stands for Mongoose ( Back end database technology )
E stands for Express ( Back end technology)
A stands for angular ( front end technology)
N stands for Node ( back end technology)
