What output will the following pseudocode produce? x = 3 do Put x to output Put " " to output x = x - 1 while x > 0

The output of the provided pseudocode will be 3, 2, 1. In this pseudocode, the do block executes first, outputting the value of x followed by a space. After that, it decrements x by 1. This process repeats until the condition of the while loop (x > 0) is no longer true.

Initially, x starts at 3. On the first iteration, 3 is outputted. Then x is decremented to 2. On the second iteration, 2 is outputted, and x is decremented to 1. On the third iteration, 1 is outputted, and x is decremented to 0.

Once x reaches 0, the condition for the while loop (x > 0) fails, and the loop terminates, meaning that 0 is never output. Therefore, the correct output produced by the pseudocode is 3, 2, 1.
