5,390,990 | 5,390,991 | Deduping a complex list using a simplified copy of itself | <p>I have two lists of strings that are passed into a function. They are more or less the same, except that one has been run through a regex filter to remove certain boilerplate substrings (e.g. removing 'LLC' from 'Blues Brothers LLC').</p>
<p>This function is meant to internally deduplicate the modified list and remove the associated item in the non-modified list. You can assume that these lists were sorted alphabetically before being run through the regex filter, and remain in the same order (i.e. original[x] and modified[x] refer to the same entity, even if original[x] != modified[x]). Relative order must be maintained between the two lists in the output.</p>
<p>This is what I have so far. It works 99% of the time, except for very rare combinations of inputs and boilerplate strings (1 in 1000s) where some output strings will be mismatched by a single list position. Input lists are 'original' and 'modified'.</p>
<pre><code># record positions of duplicates so we're not trying to modify the same lists we're iterating

<p>I know that goto operator both in C and C++ is useless in almost all situations, but i want to know the answer for this question only by interest, it has no practical meaning.</p>
<p>Does C++ standard guarantees that in such situations destructors of objects must be called properly?</p>
<pre><code>#include <iostream>
class Foo
{
public:
Foo() { std::cout << "Foo::Foo() \n"; }
~Foo() { std::cout << "Foo::~Foo() \n"; }
};
int main()
{
{
std::size_t i = 0;
_1:
Foo instance;
if (!++i)
{
goto _1;
}
}
{
Foo instance;
goto _2;
}
_2:
;
}

<p>And what about other stange situations with goto and C++ RAII?</p>
<p>It would be really cool if you can post here the quotes from the C++ standard.</p>

<p>When I read the C++ primer, there is a defined term which is <strong>predicate</strong>.</p>
<p>The definition is this :</p>
<p><strong>Functions that returns a type that can be converted to bool. Often used by the generic algorithms to test elements . predicates used by the library are either unary (taking one argument) or binary(taking two).</strong> </p>
<p>Anyone that returns a type that can be converted to bool can be predicate ! Right? Or there are some other restrictive conditions.</p>

<p>So:</p>
<pre><code>[p=='None' and None or int(p) for p in parts]
</code></pre>
<p>Doesn't work because you can't use <code>None</code> with the and/or construct reliably. (Even if <code>p=='None'</code> is true, <code>None</code> is equivalent to false so it goes to the <code>or</code> part.)</p>
<pre><code>[int(p) if p=='None' else None for p in parts]

<p>Also doesn't work. I guess it evaluates <code>int(p)</code> before the conditions? (Seems odd semantics.)</p>

for p in parts:
