Answer: b. My name is BobBob
Explanation:
- $foo = 'Bob'; // Assigns foo variable the value Bob
- $bar = $foo; // Assigns the value of foo to bar
- $bar = "My name is $bar"; //changes the $bar this is the way to include variables directly in the string.
- print $bar; // this prints My name is and moves to the variable $bar which prints the value of $bar which is the value of $foo i.e. Bob
- print $foo; // prints another Bob

Answer:
The answer is (C)
Let’s run the algorithm on a small input to see the working process.
Let say we have an array {3, 4, 1, 5, 2, 7, 6}. MAX = 7
- Now for i=0, i < 7/2, here we exchange the value at ith index with value at (MAX-i-1)th index.
- So the array becomes {6, 4, 1, 5, 2, 7, 3}. //value at 0th index =3 and value at (7-0-1)th index is 6.
- Then for i=1, i < 7/2, the value at index 1 and (7-1-1)=5 are swapped.
- So the array becomes {6, 7, 1, 5, 2, 4, 3}.
- Then for i=2, i < 7/2, the value at index 2 and (7-2-1)=4 are swapped.
- So the array becomes {6, 7, 2, 5, 1, 4, 3}.
- Then for i=3, i not < 7/2, so stop here.
- Now the current array is {6, 7, 2, 5, 1, 4, 3} and the previous array was{3, 4, 1, 5, 2, 7, 6}.
Explanation:
So from the above execution, we got that the program reverses the numbers stored in the array.
