How do you write a constraint in competitive programming?

Constraints tell you the upper and lower limit of inputs coming in. For eg. 1 <= T <=2000 would mean that the input for T would be between 1 and 2000.

How do you output a modulo?

The modulo operation is the same as ‘ the remainder of the division ‘. If I say a modulo b is c, it means that the remainder when a is divided by b is c. The modulo operation is represented by the ‘\%’ operator in most programming languages (including C/C++/Java/Python). So, 5 \% 2 = 1, 17 \% 5 = 2, 7 \% 9 = 7 and so on.

What is constraints in coding question?

Constraints are, as you said, the LIMITS (Upper and Lower) of the input data, and are VERY important when considering the solution of a problem. They give an idea of the data types to be used, approach to be adopted etc.

How do you use constraints in Python?

Basics of Using python-constraint

1. import constraint.
2. define a variable as our problem.
3. add variables and their respective intervals to our problem.
4. add built-in/custom constraints to our problem.
5. fetch the solutions.
6. go through the solutions to find the ones we need.

How do you find the modulo of a number?

How to calculate the modulo – an example

1. Start by choosing the initial number (before performing the modulo operation).
2. Choose the divisor.
3. Divide one number by the other, rounding down: 250 / 24 = 10 .
4. Multiply the divisor by the quotient.
5. Subtract this number from your initial number (dividend).

How do you add two integers to an array in Python?

Method 2: Add two list using the Comprehension List

1. # initialize the Python lists.
2. lt1 = [2, 4, 6, 8, 10, 30]
3. lt2 = [2, 4, 6, 8, 10, 12]
4. # print the original list element.
5. print ( ” Python list 1 : ” + str (lt1))
6. print ( “Python list 2 : ” + str (lt2))
7. # use list comprehension to add two lists.
