First, write a printArray() function that prints out the array. Use a single parameter in the definition of the function, and pass the array you created above as the parameter. Call the function so it prints the original array.
Then write a flipHorizontal() function that flips the contents of the array horizontally and prints the result. This means that the values in each row should be reversed (look at the second array in the sample run of the program for clarity). Again, this function should pass the original array as the parameter. Within your flipHorizontal() function, call the printArray() function to print the new array that has been horizontally flipped.
Reset the array back to the original 5 x 5 array we started with.
Then write a flipVertical() function that flips the contents of the array vertically and prints the result. This means that the values in each column should be reversed (look at the third array in the sample run of the program for clarity). Again, this function should pass the original array as the parameter. Within your flipVertical() function, call the printArray() function to print the new array that has been vertically flipped.

The proper type of data is required. Users must, for instance, enter a figure in the field labeled “Total purchase units.” There must be a limit on the data's range of values. For instance, customers can only select a legitimate loan type from a list of possibilities.
What is the input's valid data by setting algorithms?An input validation approach is used to ensure that the data given by a user is accurate.
A software might ask for a score between 0 and 50, for instance, and employ an input validation technique to make sure that numbers below 0 and beyond 50 are rejected.
Any Value—This nullifies any previous data validation. Whole Number—Only whole numbers are permitted. You might stipulate, for instance, that the user must enter a value between 0 and 30. Decimal: The user must provide a decimal-valued number.
Therefore, boundaries programmer ensures the user inputs valid data by setting algorithms boundaries data output.

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is:
As long as x is greater than 0
Output x % 2 (remainder is either 0 or 1)
x = x // 2
Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string.
Ex: If the input is:
6
the output is:
110
The program must define and call the following two functions. Define a function named int_to_reverse_binary() that takes an integer as a parameter and returns a string of 1's and 0's representing the integer in binary (in reverse). Define a function named string_reverse() that takes an input string as a parameter and returns a string representing the input string in reverse.
def int_to_reverse_binary(integer_value)
def string_reverse(input_string)

Loops are used for operations that must be repeated until a certain condition is met.
