Finding all possible combinations of numbers to reach a given sum
...e solved in exponential time O(2^n), for instance for n=10 there will be 1024 possible solutions. If the targets you are trying to reach are in a low range then this algorithm works. So for instance:
subset_sum([1,2,3,4,5,6,7,8,9,10],100000) generates 1024 branches because the target never gets to ...
Common programming mistakes for Clojure developers to avoid [closed]
...:
(let [foo (BigDecimal. "1") bar (BigDecimal. "42.42") baz (BigDecimal. "24.24")]
when in fact Clojure supports BigDecimal literals by appending M to the number:

...plementation. In my test, I hash 5 strings using all four SHA-2 versions (224, 256, 384, 512), and I loop 300 times. I measure times using Boost.timer.
