Time Complexity

In computer science, the computational complexity that is measured in terms of time is referred to as time complexity that defines how long it takes a computer to execute an algorithm. An algorithm's time complexity is measured by the the amount of time required to execute each statement of code in the algorithm. If a statement is set to execute repetitively, the number of times it will be N multiplied by the time it takes to run that function each time is equal .

Question

Computer Simulation. Use Matlab and the help menu (as well as any resource
available) to complete the following exercise.
(a) Generate a time series t = 1,000 draws. Plot and attach your (1) computer code
and (2) output from each simulation.
i. Simulate the following AR(1) process yt = a + byt-1 + Et,
and plot it. Assume a = 10, b = 0.95 and o? = 0.01.
Et ~ N(0, o2),
ii. Now assume a = 10 and b = -0.95. How does the simulation differ from
part (i)?
iii. Now assume a = 0 and b = 1 and simulate a new series. This is known as a
"random walk" and is used to model stock data such as the S&P 500.
iv. Now assume a = 10 and b = 1. This type of series is known as a "random
walk with drift."

There are many sensors on a wind turbine, based on each sensor's reading many alerts are generated as (start, end). For easier monitoring, our customer is asking to raise alerts on the turbine level instead of on each sensor. If any sensor is having an alert, there should be an alert for the entire wind turbine. Suppose the alerts created with two sensors readings are [(0,3),(5,10),(1,4),(10,15)], then the turbine level alert should be [(0,4),(5,15)]. Return the alerts sorted by the start timestamp. If there is no alert from the sensor level, return an empty array []. Code needs to be in Python?
