Summary
Implement a method that takes in an array of string based integers that returns the sum of all of the integer values.
Exercise Description
Given the following array of strings:
["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20"]
Build out a method that converts the string values to integers and then totals the integers.
Expected Output
string_sum(["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20"]) # 210
Real World Usage
This exercise will test two important development components:
- Converting a data collection to a different data type.
- Performing calculations on a collection of values.
