Write a method named lastIndexOf that accepts an array of integers and an * integer value as its parameters and returns the last index at which the * value occurs in the array. The method should return -1 if the value is not * found.

Answer:

The method is as follows:

public static int lastIndexOf(int [] numbers, int num){

    int lastIndex = numbers[0];

    for(int i =0; i<numbers.length;i+=num){

        lastIndex = numbers[i];

    }

    return lastIndex;

}

Explanation:

This defines the method

public static int lastIndexOf(int [] numbers, int num){

This initializes the lastIndex to the first element of the array

    int lastIndex = numbers[0];

This iterates through every "num" element of the array

    for(int i =0; i<numbers.length;i+=num){

This gets the current index... until the last

        lastIndex = numbers[i];     }

This returns the last

    return lastIndex; }

Create a Python dictionary that returns a list of values for each key. The key can be whatever type you want.

Design the dictionary so that it could be useful for something meaningful to you. Create at least three different items in it. Invent the dictionary yourself. Do not copy the design or items from some other source.

Next consider the invert_dict function.

def invert_dict(d):
inverse = dict()
for key in d:
val = d[key]
if val not in inverse:
inverse[val] = [key]
else:
inverse[val].append(key)
return inverse

Modify this function so that it can invert your dictionary. In particular, the function will need to turn each of the list items into separate keys in the inverted dictionary.
Run your modified invert_dict function on your dictionary. Print the original dictionary and the inverted one.
Describe what is useful about your dictionary. Then describe whether the inverted dictionary is useful or meaningful, and why.

Many Java programs that you create will receive and process user input. In order to ensure that user input is accurate, you will need to use input validation and exception handling.

a. True
b. False
