Question by Ibrahim Mesecan.
Multiply a row and add it to another
In gaussian elimination, the rows are multiplied
with a constant and added over another.
The following adds s times Rowi to Rowj
sRi + Rj --> Rj
Question:
Write a program reads a 2D array and three integers
(i, j and s). And calculates and prints the new array.
Input specification:
First, you will be two integers: the number of rows
(n) and the number of columns (m). Each of the
following n lines will contain m integer. Then,
you will be given 3 integers:(i, j and s) where
m, n, i and j are between 2 and 100, s is between
1 and 100 the numbers in 2D array are between
-1000 and +1000.
Output specification:
Show the new 2D array.
| Sample Input I |
Sample Input II |
4 3
4 7 1
2 3 10
1 10 5
1 5 6
3 2 -2

3 4
-5 10 10 9
-10 -1 -7 2
2 -6 -3 -2
3 1 2

| Sample Output I |
Sample Output II |
4 7 1
0 -17 0
1 10 5
1 5 6
|
-1 -2 4 5
-10 -1 -7 2
2 -6 -3 -2
|
Explanation:
In sample input I, there is 1 in the first array,
but it does not exist in the second array. All
the numbers in two arrays appears at least
one in two arrays in the second sample.
