Answer:
Exception is thrown and the file is created with 0 length.
Explanation:
While opening a file there is an error occur which shows the file does not exist that means an exception is thrown.
And this error can be occur when the size of the file is very very low means the file is a size of 0 length. So to avoid this error we have to exceed its length from the zero length.
Answer:
B.O(n).
Explanation:
Since the time complexity of visiting a node is O(1) in iterative implementation.So the time complexity of visiting every single node in binary tree is O(n).We can use level order traversal of a binary tree using a queue.Which can visit every node in O(n) time.Level order traversal do it in a single loop without doing any extra traversal.
Answer:
SuperFetch
Explanation:
Superfetch is a memory management technique on windows service that enables or fetch frequently use applications on systems and launch them faster because the frequently use applications has been preload into the system memory for easy access when they want to be used.
SuperFetch always takes notice of all application running on your system in which when you exit a frequently used application SuperFetch will preload them immediately since it is saved on the system memory.
One of the most important part of Superfetch is that it saves alot of time because you don't have to search the applications before you get access to them in as far as the application was frequently used.
Answer:
product_name = input("Enter product name : ")
if product_name=="pen"or"book"or"box"or"pencil"or"eraser":
if product_name == "pen":
amount = 10
print(f"Product Name: {product_name}\nCost: {amount} rupees")
if product_name == "book":
amount = 100
print(f"Product Name: {product_name}\nCost: {amount} rupees")
if product_name == "box":
amount = 150
print(f"Product Name: {product_name}\nCost: {amount} rupees")
if product_name == "pencil":
amount = 5
print(f"Product Name: {product_name}\nCost: {amount} rupees")
if product_name == "eraser":
amount = 8
print(f"Product Name: {product_name}\nCost: {amount} rupees")
else:
print("Item not found!")
Explanation:
The python program is a code of nested if-statements that compares the input string to five items of the first if-statement. For every item found, its code block is executed.
