adding n-tuplesby kwatts59 (Initiate)
|on May 16, 2019 at 13:35 UTC||Need Help??|
kwatts59 has asked for the wisdom of the Perl Monks concerning the following question:
There are two arrays, each with n numbers. How do I calculate the sum of all the possible n-tuples.
For example, array @A has 4 numbers and array @B has 4 numbers as follows:
How do I calculate the sum of all 4-tuples?
Note that there are no duplicate numbers or positions. Ex. a1*a1*a2*a2 or a1*b1*a2*b2 are not counted.
Edit: I forgot the last 4-tuple b1*b2*b3*b4
