There is an algorithm(A) I need manual help in tracing on what tthe value of the integer at index 4 is when the  ALGO(A) terminates. (The Answer for reference is 2) but  I can't seem to figure out how the program runs without using a compiler so I need a handwritten explanation

Consider the following pseudocode ALGO which takes as input an array A
containing n integers.
Assume that array indexing begins at 0.
ALGO (A)
1: x = A[0]
2: p = -1
3: r = n
4: while (True) {
do {
5:
6:
7:
8:
9:
10:
11:
10:
11:
12:
13:
14:
15:}
p = p + 1
} while (A[p] < x)
do {
r =
r - 1
} while (A[r] > x)
if (p >= r ){
return r
}
exchange A[p] and A[r]
1. Suppose the input array is A = <10, 19, 9, 7, 12, 8, 5, 4, 11, 2, 6, 3>
