PROBLEM: 3N+1 sequence: determine which value(s) of N generate the longest sequence for the famous 3N+1 sequence. Refer to 8.5 in your runestone text for more details. Output the value(s) of N that generate the longest sequence.
C version: use 100 as the value of N
Consider the following to help you better understand how to solve this problem.
OUTPUT FORMAT:
C version - a single number
What is wrong with my code?
in an experiment to measure the height of a ceiling, a pendulum bob was suspended from the ceiling so that the initial height h of the bob from the floor was 20cm. at this height, the bob was displaced and set into oscillation. the time for 20 oscillations was determined and recorded, this was repeated once and the average time t for 20 oscillations and hence, the period of oscillation t was calculated. the experiment was repeated for different heights of the bob from the floor and in each case the corresponding values of h,t1 and t2 was recorded and shown below. h(cm)= 20.00, 40.00, 60.00, 80.00, 100.00. t1= 46.30, 41.85, 37.95, 33.20, 28.85. and t2= 46.00, 41.95, 38.00, 33.35, 28.95. draw a table showing the corresponding values of h, t, t and t²
