int getPrice(int L, int W, vector > pieces) {
int vector > M(L+1, vector(W+1, 0));

不刷题也不容易的，下面是我经历的一个挑战，大家可以看看能否达到人家的要求。
这个Startup的要求是一个小时左右完成下面这个Project，下面是原文：
As I mentioned, the next step is a technical skills challenge. We expect the
exercise to take about an hour, though it is not timed.
Take-Home Challenge - Backend
* Using Java or Kotlin and framework(s) of your choice (though we like
Spring Boot), create an API that accepts a freeform search query and returns
a list of matching Flickr titles and image URLs for various sizes.
* Limit the response to ten titles.

Costco Wholesale Corp. has attained a goal that retailers have sought for
years: near-zero expenses for credit-card payments.
In a deal with Visa Inc. and Citigroup Inc., Costco’s acceptance costs will
be about zero, according to people familiar with the arrangement. That
compares with the roughly 0.6 percent of each transaction the retailer pays
its current partner, American Express Co. While Costco will still incur
small fees on Visa cards issued by other banks, incentives from Citigroup

Royal Arches (15 pitches 5.7)
Matthes Crest 5.7 (Simul-climb most of the 1-mile traverse)
这两个就是两个long day了，是前后都需要take easy的long day
West Crack (4-pitch 5.8)
South Crack (7-pitch 5.8)
Commitement (3-pitch 5.9)
Jam Crack (second pitch 5.9) 我去年被人鄙视没爬这个了。据说很不错
这些加上一些附近的路线又是至少三天了
这些都在我们目前的能力范围之内。今年一个season还能涨一些。不过基本就这些了。
Valley很多off-width，这个要单独练。我去年爬了不少off-width，今年争取多lead些
off-width。如果off-width有长进可以爬爬Central Pillar of Frenzy （5-pitch 5.9
)。不过很多人都说这条是他们爬过的最难的5.9。

In the serve fundamentals section of FuzzyYellowBalls, we suggested you
use the party stance when you were first learning the serve because it’s
a very simple stance and lets you execute all of the fundamentals of the
serve. Not only is it simple, but it is also effective. Many pros,
including Roger Federer, use the party stance. To quickly review, the
party stance is where your feet are ab... 阅读全帖

Achieve “Real” Flexibility For me, every practice, every workout, every
match starts the same way: ten to fifteen minutes of movement. That’s
running or biking in the fitness center, followed by dynamic stretching on
the sidelines. None of this is too intense—it’s just to warm up my muscles
. If I’m on the bike, it’s set on level 1 or 2. Because I must be
extremely aware of the potential for injury, I don’t play even a fun
exhibition charity match without a proper warm-up. Safety ... 阅读全帖

Maybe you can consider comparing the widths of peaks (i.e. widths at the
half maxima of the peaks) in the probability distributions for tooth paste
and Xmas trees.
The width of the peaks of probability for products like Xmas tree will be
smaller than that for products like tooth paste and groceries.
If it is possible for a product to have multiple peaks in its probability
distribution, you might want to consider the mean of the widths.
3. Given the SAS data set SASUSER.HOUSES:
The following SAS program is submitted:
