HTTP middleware provide a convenient mechanism for filtering HTTP requests entering your application. For example, Laravel includes a middleware that verifies the user of your application is authenticated. If the user is not authenticated, the middleware will redirect the user to the login screen.

To soft delete a model you may use: $model = Contents::find( $id ); $model->delete(); Deleted (soft) models are identified by the timestamp and if deleted_at field is NULL then it's not deleted and using the restore method actually makes the deleted_at field NULL .

Is it possible to have a recursive inline function?
Although you can call an inline function from within itself, the compiler may not generate inline code since the compiler cannot determine the depth of recursion at compile time.

This problem seems easy at first glance so a careless developer might write something like this: void F(int* A, int* B, int N) { int m = 1; for (int i = 0; i < N; ++i) { m *= A[i]; } for (int i = 0; i < N; ++i) { B[i] = m / A[i]; } } This will work for the given example, but when you add a 0 iRead more
This problem seems easy at first glance so a careless developer might write something like this:
void F(int* A, int* B, int N) {
int m = 1;
for (int i = 0; i < N; ++i) {
m *= A[i];
}
for (int i = 0; i < N; ++i) {
B[i] = m / A[i];
}
}
This will work for the given example, but when you add a 0 into input array A, the program will crash because of division by zero. The correct answer should take that edge case into account and look like this:
void F(int* A, int* B, int N) {
// Set prod to the neutral multiplication element
int prod = 1;
for (int i = 0; i < N; ++i) {
// For element “i” set B[i] to A[0] * … * A[i – 1]
B[i] = prod;
// Multiply with A[i] to set prod to A[0] * … * A[i]
prod *= A[i];
}
// Reset prod and use it for the right elements
prod = 1;
for (int i = N – 1; i >= 0; –i) {
See less// For element “i” multiply B[i] with A[i + 1] * … * A[N – 1]
B[i] *= prod;
// Multiply with A[i] to set prod to A[i] * … * A[N – 1]
prod *= A[i];
}
}
The presented solution above has a Big O complexity of O(N). While there are simpler solutions available (ones that would ignore the need to take 0 into account), that simplicity has a price of complexity, generally running significantly slower.
