What are the benefits of vectors over arrays in terms of performance?
In PYTHON
Define a vector of integers with 5 elements
Write the following function
Given a vector and two indexes, returns a vector where the values at the provided indexes are swapped
Example Input: my_vector = [40,51,62,73,84,95]
Invokefunction:swap(my_vector,2,4)
Output:[40,51,84,73,62,95]
Why do vectors outperform arrays in terms of speed?

- Vector Arithmetics M A function named arithGym requires an input variable h, and returns three outputs: (1) column vector u, column vector z. and scalar variable count. The input variable h is a column vector of random numbers with values between 100 and 100. The length of h is also randomly chosen between 30 and 60 elements. Perform the following operations. 1. Calculate u with the same length as h that has evenly spaced values ranging from the minimum value in h to the maximum value in h. 2. Each element of column vector z is equal to the square of the corresponding element in h divided by 2 times the corresponding element in u 3. Compute the scalar variable count that counts the number of instances an element in z has a value less than the value of the corresponding element in h. Make sure to assign the results to the output variables as indicated Solve this problem using only vectorized code with no loops or if statements. Note the variable h is defined as a function input.
