Some instructions for how to read inputs and print outputs Python

a = input()

reads a line of input and stores it as a string at "a" So if you want to read a input like

12 34 53

Just do

inp = input()
inp_split = inp.split(' ')
a = int(inp_split[0])
b = int(inp_split[1])
c = int(inp_split[2])

To output things, use

print(a)

to output a string "a" on a line.

Java There are multiple ways using System.in stream. My preferred method is:

BufferedReader f = new BufferedReader(new InputStreamReader(System.in));
a = f.readLine();

"f.readLine()" reads a line of input as string and stores it in "a". To output, simply use

System.out.println(a);

to print a line of output "a"

C++

string value;
cin >> value; // takes in the value input
cout << value; 

You MAY look up ways to get inputs on the internet. You MAY use API references for your language. However, we trust you not to look up particular algorithms and problems.
