# Dimension of dynamic multi-dimensional mass

• In the NxM size matrix, rationalize the elements of zero cell columns by increasing by simple insertion.

My sorting looks like:

``````for (int i = 0; i < m; i++) {
for (int j = 0; j < n; j++) {
if (!matrix[j][i]) {
for (i = 0; i < m; i++) {
int min = i + 1;
for (j = i+2; j < n; j++) {
if (matrix[j][i] < matrix[min][i]) {
min = j;
if (matrix[min][i] < matrix[j][i]) {
int t = matrix[min][i];
matrix[min][i] = matrix[j][i];
matrix[j][i] = t;
}
}
}
}
break;
}
}
}
``````

But it doesn't work, it doesn't sort anything, tell me how to fix it, thank you in advance!

• First of all, the boxing is different.

Second, the external cycle variables i, j are used as internal enumerators and cannot operate. Didn't the compilator warn you of such non-use?

Like this (not tested):

``````  if (!matrix[j][i]) {
for (k = 1; k < n; k++) {
int temp = matrix[k][i];
int l = k;
while (l>0) & (temp<matrix[l-1][i]) {
matrix[l][i] = matrix[l-1][i];
l--;
}
matrix[l][i] = temp;
}
break;
}
``````
