Question

a algorithm whether a number is a single digit number,
two-digit number, three-digit number, four-digit number or just more than four-digit number

Answer 1

Answer:

For the above given algorithm the input 9 and 99 will give wrong output.

For input 9 the above algorithm will give ‘Double Digit’ as the condition for a single digit written as Number < 9.

Same for 99 the above algorithm will give ‘Big’ as the condition for double digit written as Number < 99.

Correct Algorithm:

INPUT Number

IF Number <= 9

"Single Digit"

Else If Number <= 99

"Double Digit"

Else

"Big"
