Code has already been provided to define a function named examstats that receives column vectors of student test scores for three different exams as inputs into three variables: exam$1$scores, exam$2$scores, and exam$3$scores. The position of each individual student's score is consistent through the three input vectors $($e$.$g$.$ the score for student number $5$ is the fifth element in each of these vectors$).$ Add code to this function to do the following:

Compute the mean test score for each student $($i$.$e$.$ the average of the student's three scores$)$ and assign these values as a column vector to the output variable named studentMeans.

Use the appropriate built$-$in function to compute the mean score for each exam and assign these three values to a row vector named exammeans with the mean scores for exams $1,2,$ and $3$ as the first, second, and third elements respectively.

Use the appropriate built$-$in function to compute the standard deviation for each exam and assign these three values to a row vector named examstDev with the results for exams $1,2,$ and $3$ as the first, second, and third elements respectively.

Solve this problem using vectorized code $($i$.$e$.$ do not use a loop in your solution$).$ Note the variables exam$1$scores, exam$2$Scores, and exam$3$scores are assigned values as function inputs. Do not overwrite these values in your code.
