Rotate Right k cells (use python)
Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly.
Example:
source=[10,20,30,40,50,60]
rotateRight(source,3)
After calling rotateRight(source,3), printing the array should give the output as:
[ 40, 50, 60, 10, 20, 30]
Indicate true or false for the following statements:
Every element in an array has the same type.
The array size is fixed after it is declared.
The array size declarator must be a constant expression.
The array elements are initialized when an array is declared.

- Shift Right k Cells (Use Python) Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftRight(source,3) After calling shiftRight(source,3), printing the array should give the output as: [ 0,0,0,10,20,30 ]arrow_forwardMethod Details: public static void rotate(int[] array, boolean leftRotation, int positions) Rotates the provided array left if leftRotation is true; right otherwise. The number of positions to rotate is determined by positions. For example, rotating the array 10, 20, 7, 8 two positions to the left will update the array to 7, 8, 10, 20. Only arrays with 2 or more elements will be rotated. Hint: adding private methods that rotate an array one position to the left and one position to the right can help. Parameters: array - leftRotation - positions - Throws:java.lang.IllegalArgumentException - When a null array parameter is providedarrow_forward(FYI: Pseudocode is required (Not any programming language) Design a pseudocode program that loads an array with the following 7 values. Add one more word (of your own choosing) for a total of 8 words. biffcomelyfezmottleperukebedraggledquisling Be sure to use lowercase, as shown above. This will make the processing easier. Ask the user to enter a word Search through this array until you find a match with the word the user entered. Once you find a match, output "Yes, that word is in the dictionary". If you get to the end of the array and do NOT find a match, output "No, that word is not in the dictionary". The program should work with any set of words in the arrays. If I were to change the words in the arrays, it should still work. If you need help, look at the search example in your textbook.arrow_forward

A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character.

- 1.Answer the following questions: 1(a) Write a method to compute and return the value of maxEven and minOdd where maxEven is the largest even element of an int array and minOdd is the smallest odd element of the int array. The method is passed the int array and an int value that denotes the number of elements in the array. You may assume that the int array has at least 1 element in it. 1(b) Write a method to compute and return the value of countEven and countOdd where countEven is the number even elements in an int array and countOdd is the number of odd elements in the int array. The method is passed the int array and an int value that denotes the number of elements in the array.

Performing addAt(20, 2) in the example list will add 20 at the 2nd position and the array will now look like this: [10, 20, 30, 40, 50] When the value of pos is greater than the size + 1 or less than one, output "Position value invalid" void removeAt(int pos) Removes the number in the posth position of the list. Performing removeAt(3) in the example list will remove the 3rd element of the list and the updated array will be: [10, 30, 50] When the value of pos is greater than the size or less than one, output "Position value invalid" void removeAll(int num) Removes all instances of num in the array list. In this array [10, 10, 20, 30, 10], performing removeAll(10) will remove all 10's and the list will look like this: [20,…arrow_forwardJava Programming [ Using Array] - 1arrow_forward
