Question
.If the elements “Bâ€, “Oâ€, “M†and “B†are placed in a stack and are deleted one at a time, what is the order of removal?a) BOMB b) BMOB c) MBBO d) BBOM
Solution
The order of removal for a stack follows the principle of "Last In, First Out" (LIFO). This means that the last element that was added to the stack will be the first one to be removed.
Given the stack elements are "B", "O", "M", and "B" in that order, the order of removal would be:
- The last "B" added to the stack is removed first.
- Then "M" is removed.
- Followed by "O".
- And finally, the first "B" is removed.
So, the order of removal is "BMBO". Therefore, the correct answer is (b) BMOB.
