Transcribed Image Text:QUESTION 8
The following algorithm construct a sequence of positive whole numbers, which demonstrates the famous Collatz's conjecture: starting from any
positive whole number, the sequence will eventually go down to 1.
1. input: positive integer x
2. i+0
3. repeat
3.1. i+i+1
3.2. if x is odd then
3.2.1. x (3 x x) + 1
else
3.2.2. x x+ 2
until x = 1
4. output i
By tracing the algorithm, how many times does the algorithm perform Step 3.2.1. if the input is set to x = 6?
