When writing a program to add two numbers entered by a user and then display the result, which of the following pseudocode snippets most completely and accurately represents this process?
BEGIN Input firstNumber Set sum to firstNumber plus secondNumber Output sum END
BEGIN Prompt user for firstNumber and secondNumber Output firstNumber, secondNumber END
BEGIN Input firstNumber Input secondNumber Set sum to firstNumber plus secondNumber END
BEGIN Input firstNumber Input secondNumber Set sum to firstNumber plus secondNumber Output sum END
The correct snippet follows a clear input-process-output sequence: it begins the program, collects both user inputs, calculates the sum in a separate variable, outputs that sum, and then ends. Each distractor is missing at least one essential step (a second input, the calculation, or the output).
