You is climbing a stair case. It takes n steps to reach the top.Each time you can either climb 1 or 2 steps. In what many distinct ways can you climb to the top?Analysis:There are a total of n steps, you can take one step at a time, you can walk two steps at a time, how many different ways to go?This problem is similar to a small robot finding a unique path problem,For a certain step I, there are two possible ways to reach it, one may be from its previous level, and one may be from its previous

Speed/quality trade-off from 1 (brute-force) to ten (fastest). The default is 3. Speed ten have 5% lower quality, but is 8 times faster than the default.

Workaround for IE6, which only displays fully opaque pixels. Would make pngquant almost-opaque pixels fully opaque and would avoid creating new transparent colors.
You is climbing a stair case. It takes n steps to reach the top.Each time you can either climb 1 or 2 steps. In what many distinct ways can you climb to the top?Initially want to use the arrangement of the way, but the formula is not very good, and then want to use a recursive way, finally left a step 1, and finally left 2 steps two, and then that step equivalent to n-1 steps of the total number of methods plus n-2 steps of the total number of methods, but this will time out.Finally, the loop in

I passed the 70-561 exam on Friday afternoon and did not answer questions. I did it myself. In fact, this course was tested once a year ago. At that time, I thought ADO.

Taking advantage of the Spring Festival holiday, I had a good preparation and finally passed the course.
