How to generate a random string of a fixed length in Go?
...For that, Paul's solution is perfect. This is if performance does matter. Although the first 2 steps (Bytes and Remainder) might be an acceptable compromise: they do improve performance by like 50% (see exact numbers in the II.

Find the nth occurrence of substring in a string
...
Mark's iterative approach would be the usual way, I think.
Here's an alternative with string-splitting, which can often be useful for finding-related processes:
def findnth(haystack, needle, n):
parts= haystack.split(needle, n+1)

return -1
return len(...

[--] <path>…
Show only commits that affect any of the specified paths. To prevent confusion with

from options or refnames.
