Learn how to solve No Idea! problem on HackerRank using Python. The problem involves an array of integers and two sets of liked and disliked numbers. See input, output, and code examples.
- Using Map and counter methods. Python's map() is a built-in function that allows you to process and transform all the items in an iterable without using an explicit for loop, a technique commonly known as mapping.
- Using List comprehension. A Python list comprehension consists of brackets containing the expression, which is executed for each element along with the for loop to iterate over each element in the Python list.
- Using for loop. Let us now use the for loop and find out the solution as required in the question. # taking input from the user a=input().split(' ') l=([int(i) for i in input().split(' ')]) # converting to set firstset=set([int(i) for i in input().split(' ')]) secondset=set([int(i) for i in input().split(' ')]) # initalizing with zero p=0 # using for loop with if statements for i in l: if i in firstset: p+=1 if i in secondset: p-=1 # printing print(p)
- Using __name__ variable. In Python, the special name __main__ is used for two important constructs: the name of the top-level environment of the program, which can be checked using the __name__ == '__main__' expression.
