To solve this problem, we need to take two numeric strings from the input list, sum their integer values, and return the result as a string.

Approach

1. Extract Input Values: The input is a list containing two numeric strings.
2. Convert to Integers: Convert each string in the input list to an integer.
3. Sum the Integers: Add the two integers together.
4. Convert Back to String: Convert the sum back to a string to get the output.

Solution Code

def sum_numeric_strings(input_list):
    return str(int(input_list[0]) + int(input_list[1]))

# Example usage (matching the given input/output)
input_data = ["123", "123"]
output = sum_numeric_strings(input_data)
print(output)  # Output: "246"

Explanation

• Extraction: The input list ["123", "123"] is taken as input.
• Conversion: Each string ("123" and "123") is converted to the integer 123.
• Sum: The sum of 123 + 123 is 246.
• String Conversion: The integer 246 is converted back to the string "246", which is the final output.

This approach efficiently handles the problem with a time complexity of O(1) since we are dealing with a fixed number of elements (two) and basic arithmetic operations. The space complexity is also O(1) as we only store a few variables.
