Consider the following selection statement where X is an integer test score between 0 and 100.

input X if (0 <= X and X < 49)
output "you fail"
else if (50 <= X and X < 70)
output "your grade is" X
output "you did OK"
else if (70 <= X and X < 85)
output "your grade is" X
output "you did well"
else if (85 <= X and X < 100)
output "your grade is" X
output "you did great"
endif
output "how did you do?"

Math assistance needed.

To determine the output based on the given input score, you need to follow these steps:

1. Take an input value for the test score, denoted as X.
2. Check the conditions of the selection statement to see which range X falls into.

- If X is greater than or equal to 0 and less than 49, the output will be "you fail."
- If X is greater than or equal to 50 and less than 70, the output will be "your grade is X" (where X is the input value of the test score) and "you did OK."
- If X is greater than or equal to 70 and less than 85, the output will be "your grade is X" and "you did well."
- If X is greater than or equal to 85 and less than 100, the output will be "your grade is X" and "you did great."

3. Regardless of the condition, the program will always output "how did you do?" at the end.

It is important to note that the given selection statement assumes that X will be an integer between 0 and 100. If X is outside this range, the program will not provide the desired output.
