Okay, that's a naked question.

The answer is "yes", if 6 is a decimal number and 110 is a binary number. Now for any pair of positive integers N1 and N2, your task is to find the radix of one number while that of the other is given. Input specification: Each inp

Later I found that this question was required to arrive at a given point in time. It was neither early nor late, BFS finds the shortest time and does not answer the question each time. Therefore, it switches to DFS. The pruni

Pat 1010 Radix

After a day, I felt like I was not doing anything. I wanted to make up for my questions. I was thinking about what to do. My roommate said I 'd try Pat 1010. I skipped this question, it seems that this pass rate (0.07) is a bit exaggerated. The question is "know one number". Calculate the base number of the other number to make the two numbers equal. Naturally, considering that binary search is used to determine the base number, numbers represent [0-9

dp/slope optimization According to the description of the topic it is easy to set out the Regulation equation: $$ f[i]=min\{f[j]+ (s[i]-s[j]+i-j-1-l) ^2 \}$$where $ $s [i]=\sum_{k=1}^{i} C[k] $$And $x$ is the $s[i]-s[j]+i-j-1$.This $x$ 's expression is really not good-looking, we are easy to find that $i-j$ can actually be combined with $s[i]-s[j]$, even if $c [i]=c[i]+1$, then $s[i]=\sum_{k=1}^{i} (c[i]+1) =\sum_{k=1}^{i}c [I]+i $, so $x=s[i]-s[j]-1$. Then merge that $-1$ with $l$, that i

Starting from S to stopping D, and arriving at t at the specified time (not early or late ). Note that each '.' can only go once. Analysis: DFS, but common DFS and TL are used, so pruning is required. We can think that if we can arrive at, but there are other points around the D point that we can step on, and we can observe that, from a point (not a D point) if the distance from point D (ABS (X-dx) + ABS (Y-dy) is an odd number, the odd number step is required, and the even number is the even n
