Algorithm
|
|
|
Step 1: Create BufferedReader object ‘br’ and
int type variables ‘n’ and 'm' to store the column and row size of the 2 D
array.
Step 2: Values of ‘n’ and 'm' are checked for
validity and if it is invalid, terminate the program otherwise create the 2 D
array 'arr'.
Step 3: Stores the values in the two dimensional
array 'arr'.
Step 4: Display the original array
Step 5: Pass the two dimensional array to
function 'sort2D()' which sends each rows of the 2 d array to 'sort()' function
which sorts the elements bubble sort technique.
