Program to find the largest product of two distinct elements in Python

Suppose we have a list of numbers, we have to find the largest product of two distinct elements.

So, if the input is like [5, 3, 7, 4], then the output will be 35

To solve this, we will follow these steps −

• curr_max := -inf
• for i in range 0 to size of nums - 1, do
  • for j in range i+1 to size of nums - 1, do
    • if nums[i] * nums[j] > curr_max, then
      • curr_max := nums[i] * nums[j]
• return curr_max

Let us see the following implementation to get better understanding −

Example

class Solution:
   def solve(self, nums):
      curr_max = float('-inf')
      for i in range(len(nums)):
         for j in range(i+1, len(nums)):
            if nums[i] * nums[j] > curr_max:
               curr_max = nums[i] * nums[j]
      return curr_max
ob = Solution()
print(ob.solve([5, 3, 7, 4]))

Input

[5, 3, 7, 4]

Output

35
