Answer:

True

Explanation:

Recursion is a powerful programming paradigm for solving problems which can be restated as a combination of subproblems of the same type. Some common examples include:

1) factorial(n) = n* factorial(n-1);

Here factorial of a number is expressed as a product of the number and the factorial of the number decremented by 1.

2) treesearch(node,value)) = treesearch(left,value) || treesearch(right,value)|| (root==value)

Here we are searching for a value in a tree. This can be expressed recursively as a boolean OR of search result on left and right subtrees and the search result for the root of the tree.

Harold has been working as a real estate agent. He has a lot of housing data to report and needs help organizing his data sheet

vitfil [10]

Answer:

Harold should go with the option C. Wrap text for the columns

Explanation:

Wrapping text in a column helps to avoid reasons to truncate columns. It helps to display the contents of a cell in multiple lines instead of just one line.

This makes the text inserted easily readable and printable.

Harold's best choice is to choose Wrap text for the columns. To do this:

Select the affected cells.
Click on the home tab
Locate the Alignment section
And click the Wrap text icon.

(PYTHON) Complete the program to print out nicely formatted football player statistics. Match the following output as closely as

loris [4]

Answer:

quarterback_stats = {

'Aaron Rodgers': {'COMP': 371, 'YDS': 4925, 'TD': 39, 'INT': 8},

'Peyton Manning': {'COMP': 400, 'YDS': 4659, 'TD': 37, 'INT': 11},

'Greg McElroy': {'COMP': 19, 'YDS': 214, 'TD': 1, 'INT': 1},

'Matt Leinart': {'COMP': 16, 'YDS': 115, 'TD': 0, 'INT': 1}

}

print("2012 quaterback statistics: ")

print("Passes completed: ")

for qb in quaterback_stats.keys():

print(f"{quaterback_stats[qb]} : {quaterback_stats[qb]['COMP']}")

print("Passing yards:")

for qb in quaterback_stats.keys():

print(f"{quaterback_stats[qb]} : {quaterback_stats[qb]['YDS']}")

print("Touchdown / interception ratio")

for qb in quaterback_stats.keys():

if quaterback_stats[qb]['TD'] > 0 and quaterback_stats[qb]['INT'] > 0:

print(f"{quaterback_stats[qb]} : {float(quaterback_stats[qb]['TD']) / float(quaterback_stats[qb]['INT])}")

else:

print(f"{quaterback_stats[qb]} : {0.0}")

Explanation:

The python program gets data from a dictionary called quaterback_stats which holds the data of football players with their names as the keys and a list of records as the value.

The program prints the individual records from the dictionary using a for loop statement on the list of dictionary keys (using the keys() method).
