This debug error means that the stack pointer register is not returned to its original value after the function call, i.e. that the number of pushes before the function call were not followed by the equal number of pops after the call. There are 2 reasons for this that I know (both with dynamically loaded … Read more
This should be bitwise OR’d or you end up overwriting the earlier flag. intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); Like so: intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
A stack is a LIFO data structure (last in, first out, meaning last entry you push on to the stack is the first one you get back when you pop). It is typically used to hold stack frames (bits of the stack that belong to the current function). This may include, but is not limited … Read more
First, it’s platform dependent. In some architectures, stack is allocated from the bottom of the address space and grows upwards. Assuming an architecture like x86 that stack grown downwards from the top of address space, the idea is pretty simple: =============== Highest Address (e.g. 0xFFFF) | | | STACK | | | |————-| <- Stack … Read more
Kotlin 1.3.70 introduced the kotlin.collections.ArrayDeque class, which functions as both a queue and a stack, like Java’s java.util.Deque (Deque meaning “double-ended queue”). It was created out of a necessity for a multiplatform ArrayDeque implementation. val stack = ArrayDeque(listOf(1, 2, 3)) // stack: [1, 2, 3] stack.addLast(0) // stack: [1, 2, 3, 0] (push) val value … Read more
Increasing the stack size will only serve as a temporary bandage. As others have pointed out, what you really want is tail call elimination, and Java does not have this for various reasons. However, you can cheat if you want. Red pill in hand? OK, this way please. There are ways in which you can … Read more
Space (not time) efficient. You could: 1) Define two stacks beginning at the array endpoints and growing in opposite directions. 2) Define the third stack as starting in the middle and growing in any direction you want. 3) Redefine the Push op, so that when the operation is going to overwrite other stack, you shift … Read more
You’ve been to a cafeteria, right? and seen a stack of plates? When a clean plate is added to the stack, it is put on top. When a plate is removed, it is removed from the top. So it is called Last-In-First-Out (LIFO). A computer stack is like that, except it holds numbers, and you … Read more
There is no pop method for NumPy arrays, but you could just use basic slicing (which would be efficient since it returns a view, not a copy): In [104]: y = np.arange(5); y Out[105]: array([0, 1, 2, 3, 4]) In [106]: last, y = y[-1], y[:-1] In [107]: last, y Out[107]: (4, array([0, 1, 2, … Read more
Best solution would be instead of using Static data, use Shared Preferences or store data in a Database and if any uncaught Exception occurs, show a message like Application has crashed and a report is sent to the admin and then restart the Activity that caused the Crash. This way user can continue using the … Read more
