Question

Python please!

Exercise #3: Design and implement a program (name it ArrayMethods), that defines 4 methods as follows:

int arrayMax(int[] arr) returns the maximum value in the an array

int arrayMin(int[] arr) returns the minimum value in an array

void arraySquared(int[] arr) changes every value in the array to its square (value²)

void arrayReverse(int[] arr) reverses the array (for example: array storing 7 8 9 becomes 9 8 7 )

The program main method creates a single-dimensional array of length 5 elements and initialize it with random integers between 1 and 100. The program displays the original array, then calls each of the above methods and displays their results as shown below. Document your code and organized your output following these sample runs.

Answer 1

Thats it !!! here is the code

---------------------------------------------------------------------------------------------------------------------------------

import random
#int arrayMax(int[] arr) returns the maximum value in the an array
def arrayMax(arr):
    highest_num=0
    for num in arr:
        if highest_num<num:
            highest_num=num
    return highest_num

# int arrayMin(int[] arr) returns the minimum value in an array
def arrayMin(arr):
    smallest_num=100
    for num in arr:
        if smallest_num>num:
            smallest_num=num
    return smallest_num

#void arraySquared(int[] arr) changes every value in the array to its square (value²)
def arraySquared(arr):
    return [x*x for x in arr]

#void arrayReverse(int[] arr) reverses the array (for example: array storing 7 8 9 becomes 9 8 7 )
def arrayReverse(arr):
    reverse_array=[]
    for i in range(len(arr)-1,-1,-1):
        reverse_array.append(arr[i])

    return reverse_array


def main():
    # create a list of 5 numbers in the range of 1 to 100
    random_array=[random.randint(1,100),random.randint(1,100),random.randint(1,100),\
                  random.randint(1,100),random.randint(1,100)]

    print("Original Array:",random_array)
    print("Max Number:",arrayMax(random_array))
    print("Min Number:",arrayMin(random_array))
    print("Squared Array:",arraySquared(random_array))
    print("Reversed Array:",arrayReverse(random_array))

if __name__ == '__main__':
    main()

thank You !!!

plz a thumbs up : )

Answer 2

def arrayMax(arr):
    largest = arr[0]
    for num in arr:
        if num > largest:
            largest = num
    return largest


def arrayMin(arr):
    smallest = arr[0]
    for num in arr:
        if num < smallest:
            smallest = num
    return smallest


def arraySquared(arr):
    for i in range(len(arr)):
        arr[i] *= arr[i]


def arrayReverse(arr):
    for i in range(len(arr)//2):
        arr[i], arr[len(arr)-i-1] = arr[len(arr)-i-1], arr[i]


array = eval(input("Enter an array in list format: "))
print("Original array: " + str(array))
print("Max value: " + str(arrayMax(array)))
print("Min value: " + str(arrayMin(array)))
arraySquared(array)
print("Squared array: " + str(array))
arrayReverse(array)
print("Reversed array: " + str(array))
