2. Rotate Left k cells Use Python
Consider an array named source. Write a
method/function named rotateLeft( source,
k) that rotates all the elements of the
source array to the left 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]
rotateLeft(source,3)
After calling rotateLeft(source,3), printing
the array should give the output as:
[ 40, 50, 60, 10, 20, 30]
1. Shift Left k Cells Use Python
Consider an array named source. Write a
method/function named shiftLeft( source, k)
that shifts all the elements of the source
array to the left 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]
shiftLeft(source,3)
After calling shiftLeft(source,3), printing the
array should give the output as:
[ 40, 50, 60, 0, 0, 0 ]

17. 2D Array Operations
Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods:
getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array.
getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array.
getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row.
getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the…
