Arrange the array rows in ascending order of the number of identical elements in each row?

Question

Arrays

Write a program that reads n > 1 rows and m > 1 columns of a two-dimensional array (mnatricei) from the keyboard and then reads those n X m array elements from the keyboard.
Arrange the rows of the array in ascending order of the number of identical elements in each row.

Answer 1

This is a trivial task. What have you tried to do yourself? Were you able to read the array? Can you count how many identical elements are in a line? Can you call the sorting algorithm?
