Extracting bits with a single multiplication
...he end, but whose carry bits end up interfering in the important un-masked range? (and note: the n-1 requirement makes sure this doesn't happen by making sure the i-1 bits after our un-masked range are clear when we shift the the ith bit)
...a...b..c...d... Potential failure on carry-bits, c is in ...
How did I get a value larger than 8 bits in size from an 8-bit integer?
...to int8_t. The subtraction in int does not overflow, and converting out-of-range integral values to another integral type is valid. If the destination type is signed, the result is implementation-defined, but it must be a valid value for the destination type. (And if the destination type is unsigned...
Get only part of an Array in Java?
...immutable. So, you need to copy the desired part as a new array.
Use copyOfRange method from java.util.Arrays class:
int[] newArray = Arrays.copyOfRange(oldArray, startIndex, endIndex);
startIndex is the initial index of the range to be copied, inclusive.
endIndex is the final index of the r...
Get a random boolean in python?
... timeit -s "from random import random" "test = [random() < 0.5 for i in range(1000000)]"
10 loops, best of 3: 118 msec per loop
$ python -m timeit -s "import numpy as np" "test = np.random.randint(2, size=1000000)"

Signed to unsigned conversion in C - is it always safe?
...um value that can be represented in the new type until the value is in the range of the new type.
Otherwise, the new type is signed and the value cannot be represented in it; either the result is implementation-defined or an implementation-defined signal is raised.
Now we need to refer to (2)...
Why can I pass 1 as a short, but not the int variable i?
...int, or ulong, provided the value of the constant-expression is within the range of the destination type.
A constant-expression of type long can be converted to type ulong, provided the value of the constant-expression is not negative.

Correct way to populate an Array with a Range in Ruby
I am working through a book which gives examples of Ranges being converted to equivalent arrays using their "to_a" methods

Python: how to print range a-z?
...work ;-) - no need to summon libraries etc - it probably expect you to use range() with chr/ord, like so:
for i in range(ord('a'), ord('n')+1):
print chr(i),
For the rest, just play a bit more with the range()
