The data in the Temp.txt file represents the change in the global surface temperature based on the average temperature between $1884$ and $2021.$ The temperatures have been recorded since $1884.$ The first column indicates the years from $1884$ to $2021.$ The second column represents the change in the global surface temperature over the world, while the third column displays the smoothed data in the change in the temperature.

Read the text file by using load function. $($The output will be a matrix$)$

Create a column vector for the time. Elements of this vector are the years from $1884$ to $2021.$

Create a column vector that shows the change in the global surface temperature without any smoothing operations.

Create a column vector that shows the change in the global surface temperature obtained by introducing smoothing operations.

Determine the maximum increase in the global surface temperature and the corresponding year. Then find the year in which the maximum increase in the temperature is recorded.

Calculate the average value of change in the global surface temperature. $($Mean of the second column of the matrix or the mean of the vector in b$.)$

Plot the change in the global surface temperature $($data without smoothing$)$ versus year. Your figure should include the necessary details $($title$,$ axis labels, and legend$)$ so that one can have a clear understanding of the data.

Add the smoothed data to the first figure. Your figure should include necessary details $($title$,$ axis labels, and legend$)$ so that one can have a clear understanding of the data

Plot the change in the global surface temperature with and without smoothing using the subplot command.
