Answer:
Worst case time of Heapsort is better than worst case time of Quicksort.
Explanation:
Worstcase of Heapsort is nlog(n). Worstcase time of Quicksort is (n^2). Heapsort is comparison based sorting algorithm. Heapsort divides input into sorting. It is a selection sort in which we send maximum inputs for maximum elements at end. Quicksort is divide and conquer algorithm. It is considered as efficient sourcing algorithm.
Answer:
1) List
2) Dictionary
3) Tuple
Explanation:
A list uses square brackets. It is used to store multiple items in just one variable. They are usually changeable and give room for duplicates. You use append to add to the collection.
A dictionary uses curly brackets. You use update to add to the collection. A dictionary is created by placing the elements in curly brackets and separating them with a comma. It is changeable and it does not give room for duplicates.
A tuple uses parentheses. You cannot change it once you create it. It is an ordered list of elements that is finite and can also store multiple items in one variable.
The elements of a good study environment are that it must be well lit the resources are near it is quite and it is clutter free
Explanation:
A good study environment must be an environment that will promote the good study conditions and it must be quite and calm if a person studies in that environment all the resources like the food water and the other refreshments must be available in that environment
The environment must be clean and it must be clutter free without any disturbances and hence these are the factors that will promote the good study environment
Answer:
Option B is the correct answer.
Explanation:
- In the above code, the loop will execute only one time because the loop condition is false and it is the Do-While loop and the property of the Do-while loop is to execute on a single time if the loop condition is false.
- Then the statement "x*=20;" will execute one and gives the result 200 for x variable because this statement means "x=x*20".
- SO the 200 is the answer for the X variable which is described above and it is stated from option B. Hence it is the correct option while the other is not because--
- Option A states that the value is 10 but the value is 200.
- Option C states that this is an infinite loop but the loop is executed one time.
- Option D states that the loop will not be executed but the loop is executed one time
