Python – Maximum product using K elements
Sometimes, while working with Python lists, we can have a problem in which we need to maximize certain numbers. There can be many conditions of maximizing. Example of that is maximizing product by using K elements. Lets discuss certain ways in which this can be performed.
Method #1 : Using
max() + sort() + list comprehension
The combination of above functions can be used to solve this problem. In this, we perform sort and then extract maximum by using the best initial or rear elements using max().
The original list is : [8, 5, 9, 11, 3, 7] Maximum product using K elements : 792
Method #2 : Using
max() + reduce() + combination() + mul + list comprehension
The combinations of above functions can be used to solve this problem. In this, we extract each possible maximum using combinations and mul is used to perform multiplication. This can be applied with any possible number of K and is recommended method to solve this. Works only for Python 2.
The original list is : [8, 5, 9, 11, 3, 7] Maximum product using K elements : 5544
