Question

Python: problem 1

Given an array of integers, return the sum of two indices from this array based on input parameters, x and y.

Example:

Given nums = [2, 7, 11, 15],  x = 3, y = 1

Because nums[x] + nums[y] = 15 + 7 = 22,
return 22.

You may use this as a template for your code

class Solution:
    def two_sum(self, nums: List[int], x: int, y: int) -> int:

Answer 1

Code:

# define a class Solution
class Solution:
    # write a method two_sum  which return sum at two input indices
    def two_sum(self, nums, x, y):
        return nums[x] + nums[y]


if __name__ == '__main__':
    # create an object of class Solution
    solution = Solution()
    # call the method to calculate sum
    # pass valid input parameters to it

    result = solution.two_sum([2, 7, 11, 15], 3, 1)

    # print the result
    print("The sum of element at index {} and {} is : {}".format(3, 1, result))

Output:

# define a class solution class Solution: # write a method two_sum which return sum at two input indices def two sum (self, nums, x, y): return nums[x] + nums [y] bif name == 'main ': # create an object of class Solution solution = Solution (). # call the method to calculate sum # pass vaid input parameters to it result = solution. two_sum ( [2, 7, 11, 15], 3, 1); # print the result print("The sum of element at index_{} and {} is : {}", format(3, 1, result))

The sum of element at index 3 and 1 is : 22, Process finished with exit code o
