selected as the last element and array A=[-23,7,-14,1,5,1]. Below is the PARTITION(4, p. r) pseudocode where pivot is always a. Illustrate the PARTITION(A, p.) module operation like below when call it with the above array A. Show clearly the position of and j in each picture.

Rewrite PARTITION(A. p. r) module above so that pivot element is always the floor of (ptt)/2. Illustrate your modified PARTITION(A, p. r) module operation like above when call it with the above array A. Show clearly the position of and j in each picture. selected as the last element and array A=[-23,7,-14,1,5,1]. Below is the PARTITION(4, p. r) pseudocode where pivot is always a.
