2. Write a program to demonstrate the knowledge of students in multidimensional arrays and looping constructs.
Eg., If there are 4 batches in BTech(IT) learning ‘ITE2005’ course, read the count of the slow learners (who have scored <25) in each batch.
Tutors should be assigned in the ratio of 1:4 (For every 4 slow learners, there should be one tutor).
Determine the number of tutors for each batch. Create a 2-D jagged array with 4 rows to store the count of slow learners in the 4 batches.
The number of columns in each row should be equal to the number of groups formed for that particular batch
( Eg., If there are 23 slow learners in a batch, then there should be 6 tutors and in the jagged array,
the corresponding row should store 4, 4, 4, 4, 4,3).
Use for-each loop to traverse the array and print the details.
Also print the number of batches in which all tutors have exactly 4 students.
