In matrix... How to find the max num in row and the same number is the min in column...?

Question

3 2 1
4 5 6
7 8 9
3 is the min and max

Answer 1

Running loops:

/*...after declaring the matrix and setting up the correspond values of the example you gave...*/

int max=matrix[0][0];
int min=matrix[0][0];
/*we assume that the first element of the matrix is both min and max, initially*/

//two loops to "run" on the matrix in the columns and the rows
for(i=0; i<3; i++){
for(j=0; j<3; j++){
if(matrix[ i ][ j ]>max) //if the actual position holds a value bigger than the current max value...
max=matrix[ i ][ j ]; //...assume that it is the next max value
if(matrix[ i ][ j ]<min) //same as the other if, but for the min value
min=matrix[ i ][ j ];
}
}

/*you can now print the value on the screen using printf and check if it is correct*/

Hope it helped :D
