How do I “git blame” a deleted line?
...
If you know the contents of the line, this is an ideal use case for:
git log -S <string> path/to/file
which shows you commits which introduce or remove an instance of that string. There's also the -G<regex> which does the same thing with regular expressions! ...
how do I initialize a float to its max/min value?
... ret.second = *begin;
}
return ret;
}
The disadvantage of providing sample code -- I see others have already suggested the same idea.
Note that while the standard has a min_element and max_element, using these would require scanning through the data twice, which could be a problem if t...
Find XOR of all numbers in a given range
...e every 4. So, that's how to arrive at that little lookup table.
Now, consider for a general range of [a,b]. We can use f() to find the XOR for [0,a-1] and [0,b]. Since any value XOR'd with itself is zero, the f(a-1) just cancels out all the values in the XOR run less than a, leaving you with the X...

JSON and XML comparison [closed]
...parsers which will change the details to make what I'm saying not quite valid.
JSON is both more compact and (in my view) more readable - in transmission it can be "faster" simply because less data is transferred.
In parsing, it depends on your parser. A parser turning the code (be it JSON or XML)...

How to check if a variable is a dictionary in Python?
...em from inheriting a bad implementation to begin with ('god object's, overriding standard library/language constructs, etc.) The original question is itself an XY problem.
