Between Two Sets

  • zubie7a + 5 comments

    Python with comprehension lists, for each number between max(setA) and min(setB), it will create a list that will hold boolean values, and 'all' checks that all the boolean values in a list are true.

    lenA, lenB = map(int, raw_input().split())
setA = map(int, raw_input().split())
setB = map(int, raw_input().split())

maxA = max(setA)
minB = min(setB)
count = 0
for num in range(maxA, minB + 1):
    left = all([num % numA == 0 for numA in setA])
    right = all([numB % num == 0 for numB in setB])
    count += left*right
print count

      Was unaware of the all function. I was trying something similar to this with list comprehensions nested in a for loop, but I was removing options from a list within the range. I understood the question, but had no concept of the methods I should use to compare every element returning True. Appreciate the knowledge. I agree with the commenter below, found this pretty difficult.

        Here is a documentation defintion from Python that defines the all and any function. Pretty useful.

      what is numA?

      • sarthakbpandey11 + 0 comments

        it's a temporary variable created while using "For Loop" to store all the iterable objects. Hope that makes sense.

      Why is the range between maxA and minB?

      def getTotalX(a, b):
    return len([1 for i in range(max(a),min(b)+1) if all([i%j==0 for j in a]) and all([j%i==0 for j in b])])

        Beautiful.
