How about a little programming session today?

Develop a program to read in 2 matrices A and B with dimensions (l X m) and (m X n) respectively, and compute and display their product AB(of dimensions (l X n)). Assume that the elements of matrices are integers. An example is shown below.(l,m,n belongs to positive integers)

Matrix A:
1 2 5
2 1 6

Matrix B:
3 4 6 4
5 6 1 2
7 8 9 9

Matrix AB:
48 56 53 53 
53 62 67 64

We recommend you to tryout the question before you check the answer.
Here is a Python code for above question.

r1,c1=input("input first matrix rows and columns:").split(" ")
m1=[]
for p in range(0,int(r1)):
    m1.append(list(map(int,input().split(" "))))
r2,c2=input("input second matrix rows and columns:").split(" ")
m2=[]
for q in range(0,int(r2)):
              m2.append(list(map(int,input().split(" "))))
if c1!=r2:
    print("invalid input")
else:
    m3=[]
    t=0
    for i in range(0,int(r1)):
        for j in range (0,int(c2)):
            for k in range(0,int(r2)):
                t=m1[i][k]*m2[k][j]+t
            m3.append(t)
            print(t,end=" ")
            t=0
        print("\n",end="")

Chances of Getting an Internship

I will tell you my story of getting an internship. My undergraduate program consisted of a six months full-time industrial training module. It allows us to experience the industry, trends, and opportunities. Continuously, the procedure is monitored by the university and the relevant authorities to make sure the outcomes of the program. Initially, there was a list of opportunities listed by the module coordinator. The list was long. There were plenty of opportunities to be a part of an engineering team. My purpose was not that simple. I wanted to be recruited by a few companies on the list. Because I always want to do exciting things that I am passionate about. I got three paid offers from robotics and industrial automation teams. My family, my mentor and the university were behind the scenes. The first thing you have to understand is yourself. Ask these questions from you. What are the technology verticals that you are passionate about? What are the skills that you already have to be a

PID control system

Image
Controlling a system is essential whenever it needs to full fill a relevant task as such. It's depending on the designer of the product. PID is one of the most common and perfect systems in control systems. PID gives us a rough idea about what it stands for. P for proportional, I for integral and D for derivative as such. Let me explain the idea of what I've absorbed from working with those basic things. What I wanted to build is a line following a smart car that used two proximity sensors to identify the white line on a black surface. I was trying with several controlling methods implemented on my own, They worked properly as well but my robot was too slow. After that I got to search for a controlling method via the internet it was found the PID controlling system for me. PID is a close loop feedback system which was full filled my requirements with a nice speedy robot. I thought that it would be better to share with what I've grabbed from them with you as well.
