Counting down to zero in contrast to counting up to length - 1
by New Jersey in Programming Languages

Is it recommended to count in small loops (where possible) down from length - 1 to zero
instead of counting up to length - 1?

1.) Counting down

for (int i = a.length - 1; i >= 0; i--) {
if (a[i] == key) return i;

2.) Counting up

for (int i = 0; i < a.length; i++) {
if (a[i] == key) return i;

Complicated SQL query - Finding a set of something, counting it, then finding a subset of the first set, and counting that
by CyberGreg in Coding

I have three tables, we'll call them table1, table2, and table3. Lets say each table has a user id column and a date column. What i'd like to do is to be able to count the number of rows with a specific user id in table1, and sum it with the number of rows with that user id in tables 2 and 3.

I'd then like to take that first query I did which has all rows with the user id, and the

counting in awk
by Ryland in Programming Languages
find ${*-.} -type f -print | xargs file |
awk '{
end {
for (i in t) printf("%d %s
", t[i], i);
}' | sort -nr

The first "find" line works. But the awk part does not work. I expect the count of file types sorted in descending order.

Counting Treaps
by sinisterDei in Development Tools & Services

Consider the problem of counting the number of structurally distinct binary search trees:

Given N, find the number of structurally distinct binary search trees containing the values 1 .. N

It's pretty easy to give an algorithm that solves this: fix every possible number in the root, then recursively solve the problem for the left and right subtrees:
