2. For each of the following statements about the behavior of ALGO, insert a T in the text box if it is True and F if it is false. A. At the end of each iteration of the while loop of Line 4, each index of A smaller than p contains an integer smaller than x. B. At the end of each iteration of the while loop of Line 4, each index of A larger than r contains an integer larger than or equal to x. C. When ALGO terminates, the integer at index r is x.

Question

Consider the following pseudocode ALGO which takes as input an array A containing n integers.

Assume that array indexing begins at 0.

2. For each of the following statements about the behavior of ALGO, insert a T in the
text box if it is True and F if it is false.
A. At the end of each iteration of the while loop of Line 4, each index of A smaller
than p contains an integer smaller than x.
B. At the end of each iteration of the while loop of Line 4, each index of A larger
than r contains an integer larger than or equal to x.
C. When ALGO terminates, the integer at index r is x.
