...ib.pyplot as plt
plt.axis([0, 10, 0, 1])
for i in range(10):
y = np.random.random()

How to determine the longest increasing subsequence using dynamic programming?
... at element with index i. To compute DP[i] we look at all indices j < i and check both if DP[j] + 1 > DP[i] and array[j] < array[i] (we want it to be increasing). If this is true we can update the current optimum for DP[i]. To find the global optimum for the array you can take the maximum v...

...hat can be evaluated down to a constant while maintaining good readability and allowing slightly more complex processing than just setting a constant to a number.

Append an array to another array in JavaScript [duplicate]
...rray1, array3);
I used .apply to push the individual members of arrays 2 and 3 at once.

array1.push.apply(array1, array2.concat(array3));
To deal with large arrays, you can do this in batches.

How can I escape white space in a bash loop list?
...t -mindepth 1 -type d -print0)
You can also populate an array from find, and pass that array later:

myarray+=( "$n" )
done < <(find test -mindepth 1 -type d -print0)
printf '%q\n' "${myarray[@]}" # printf is an example; use ...
