|How to list an image sequence in an efficient way? Numercial sequence comparison in Python|
| by Mark W in Programming Languages|
I have a directory of 9 images:
I would like to be able to list them
in an efficient way, like this (4 entries for 9 images):
(image_000[1-3], image_00[10-11], image_0011-[1-3], image_9999)
Is there a way in python, to return a directory
|How to generate a predictable shuffling of a sequence without generating the whole sequence in advance?|
| by JoeKaras in Programming Languages|
The following python code describes exactly what I want to achieve for a
sequence of arbitrary size (population):
fixed_seed = 1 #generate the same sequence every time with a fixed
population = 1000
sample_count = 5 #demonstration number
num_retries = 3 #just enough to show the repeatable behaviour
trynum in xrange(num_retries):
|Can clojure convert string representing a sequence back to a sequence?|
| by Ben Kohn in Development Tools & Services|
I can convert a string to a sequence, and then convert that sequence to
a string representing the sequence.
user=> (str (first
(list (seq "(xy)z"))))
"(( x y ) z)"
I can also
insert apply into the above form to get the original string back
user=> (apply str (first (list (seq "(xy)z"))))
but is there
|Intermixed sequence of Push and pop operations why is this sequence not possilbe|
| by FriendL in Programming Languages|
Hi everyone I'm studying for a final and I cant figure this question
Suppose that a client performs an intermixed sequence of
stack push and pop operations. The push operations push the integers 0
through 9 in order on to the stack; the pop operations print out the return
value. Which of the following sequences could not occur?
(a) 4 3 2 1 0 9 8 7 6 5
|create a random sequence, skip to any part of the sequence|
| by Trevor Cortez in Coding|
In Linux. There is an srand() function, where you supply a seed and it
will guarantee the same sequence of pseudorandom numbers in subsequent
calls to the random() function afterwards.
Lets say, I want to
store this pseudo random sequence by remembering this seed value.
Furthermore, let's say I want the 100 thousandth number in this pseudo
random sequence later.

|how to create a sequence without using mapping variables and sequence generator?|
| by eroi in Web Design|
I had a scenario where i have to generate a sequence without using
i can do the same using mapping
variables like using the
setcountvariable() option it works
but is there any other solution for the same.
