You are given the first names, middle names or initials, and last names of several people below. Use Excel text functions to transform the names such that the last name appears tirst, followed by the first name. The transformed names to be listed in the last column $($column F$-$ 'Last name First name'$)$ will not include the middle names or the initials. Follow the steps outlined below to arrive at the final output.

Step $1-$ Find the position of the first space in column 'Space $1\text{'}$

Step $2-$ Find the position of the second space in column 'Space $2\text{'}$

Step $3-$ Use the output in the 'Space $1$'column to extract the first name $($Eg$.$ 'Gregory' in case of the first person$)$ to the 'First' column.

Step $4-$ Use the output in the 'Space $2\text{'}$ column to extract the last name $($Eg$.$ 'Winston' in case of the first person$)$ to the 'Last' column.

Step $5-$ Combine the output in 'First' and 'Last'in a way that the final output appears as Last name First name $($Eg$.$ 'Winston Gregory' in case of the first person$)$ in the 'Last name First name' column.
