An algorithm to find the average of the values in an array uses the steps shown. Which two steps of the algorithm should be switched to result in success?
Steps 1 and 2 should be switched to result in success.
In the algorithm for finding the average of values in an array, step 1 typically involves initializing a sum variable, while step 2 usually entails starting the loop to iterate through the array. Switching these steps is necessary to ensure the sum is calculated correctly before any iterations begin.
Switching steps 1 and 4 would not yield success, as step 4 typically involves the final calculation or output of the average. This step should be executed after the sum has been correctly computed, which is not ensured by switching it with the initialization step.
Interchanging steps 1 and 5 would also not work. Step 5 generally relates to displaying the result or final average, which should occur after all calculations have been completed. Therefore, this switch would disrupt the logical flow of the algorithm.
Switching steps 1 and 2 ensures that the initialization of the sum occurs before entering the loop that processes the array elements. This change is crucial as it allows the algorithm to accumulate values correctly, leading to a successful calculation of the average.
Changing steps 2 and 4 would disrupt the loop's execution order. Step 2 typically involves starting the iteration through the array, while step 4 usually pertains to the final calculation. This switch would prevent the proper accumulation of the sum before computing the average.
In algorithms for calculating averages, the correct order of steps is vital for successful execution. By switching steps 1 and 2, the algorithm ensures that the sum is initialized before iterating through the array, allowing for accurate computation of the average. Other combinations would disrupt the logical sequence necessary for obtaining the correct result.
