It seems like you're using MySQL version that support window function. If so, then try this:

I believe the problem is with your final while loop.

The problem is that you are running through Str (your original string), looking for opening parentheses. However, your original string 4 + 3 ) * 4 - 2 ) * 6 - 6 ) ) ) does not contain any opening parentheses, so Str.charAt(j)=='(' is never true and temp never gets incremented to match pr. Hence the condition temp!=pr is always true, so the while loop keeps executing.

You probably want to change all occurrences of Str in this loop to Strr, which is the string you have been inserting opening parentheses into.

You will then reach a problem with the following line:

This is almost valid JSON, except the final line seems to be truncated. Pandas can import dictionaries with almost no pain:

The problem is that scribble/html is not connected to scribble/manual, and the "element" constructed there is an HTML element. You can't use the functions from scribble/html in a document like this.

If you want a block quote in scribble, you probably want to use nested-flow.

You're confusing equality checks with pattern matching. Intuitively, all of the following should be the same:

Removed

looks like you want join normally and do left_join

One would typically save the futures as values:

There's 2 questions here:

a) How to execute INVD (unsafely)

For this, you need to be running at CPL=0, and you have to make sure the CPU isn't using any "processor reserved memory protections" which are part of Intel's Software Guard Extensions (an extension to allow programs to have a shielded/private/encrypted space that the OS can't tamper with, often used for digital rights management schemes but possibly usable for enhancing security/confidentiality of other things).

Note that SGX is supported in recent versions of Linux, but I'm not sure when support was introduced or how old your kernel is, or if it's enabled/disabled.

If either of these isn't true (e.g. you're at CPL=3 or there are "processor reserved memory protections) you will get a general protection fault exception.

b) How to execute INVD Safely

For this, you have to make sure that the caches (which includes "external caches" - e.g. possibly including things like eDRAM and caches built into non-volatile RAM) don't contain any modified data that will cause problems if lost. This includes data from:

• IRQs. These can be disabled.

• NMI and machine check exceptions. For a running OS it's mostly impossible to stop/disable these and if you can disable them then it's like crossing your fingers while ignoring critical hardware failures (an extremely bad idea).

• the firmware's System Management Mode. This is a special CPU mode the firmware uses for various things (e.g. ECC scrubbing, some power management, emulation of legacy devices) that't beyond the control of the OS/kernel. It can't be disabled.

• writes done by the CPU itself. This includes updating the accessed/dirty flags in page tables (which can not be disabled), plus any performance monitoring or debugging features that store data in memory (which can be "not enabled").

With these restrictions (and not forgetting the performance problems) there are only 2 cases where INVD might be sane - early firmware code that needs to determine RAM chip sizes and configure memory controllers (where it's very likely to be useful/sane), and the instant before the computer is turned off (where it's likely to be pointless).

Guesswork

I'm guessing (based on my inability to think of any other plausible reason) that you want to construct temporary shielded/private area of memory (to enhance security - e.g. so that the data you put in that area won't/can't leak into RAM). In this case (ironically) it's possible that the tool designed specifically for this job (SGX) is preventing you from doing it badly.
