If you watch the surface of a frozen pond slowly melt on an atypically warm winter afternoon, and watch the same thing occur on the surface of a nearby good-sized frozen puddle, you might observe the ice in each appear to be transformed to water at about the same rate. But what if al...

在hash 值不同时,两个数据一定不一样;在 hash 值相同时,两个数据有极大概率一样。 字符串哈希值:f(s)=∑si⋅basel−i(modM)f(s)=∑si⋅basel−i(modM)。hash 的模数 MM 要比最大字符大,最好为质数。 子串哈希值: f(s[l:r])=f(s[1:r])−f(s[1:l−1])⋅baser−l+1f(s[...
Define a pipeline flowing system to begin the calculation. As an example, if water has to be pumped through a 2-inch Schedule 40polyvinyl chloride (PVC) pipefrom a well to a pond 400 feet away,calculatehow many gpm the system is delivering. The pressure gauge on the pipe at the well ...
These boundary conditions can represent real boundaries such as concrete walls or the surface of a pond, or can be used to represent an artificial infinite system using a periodic boundary condition. These are useful when representing a large system consisting of many repeated units. Computer codes...
一些技巧与思想也会归类于数据结构。 D - 数据结构 序列结构 树状数组 \(\mathrm{lowbit}(x)\) 函数:表示 \(x\) 的二进制表示中,最低位的 \(1\) 的数值大小,lowbit(x) = x & -x。 \(c_i\) 的管辖区间:\([i - \mathrm{
But what if all of the sunlight falling on the exposed surface of the pond, maybe an acre in size, was simultaneously focused on the surface of the puddle? Your intuition probably tells you that not only would the surface of the puddle melt into water very quickly, but the entire puddle...
According to the elasticity constitutive relation, stress_vector = C_matrix * strain_vector, where the vector has a size of 6, and C_matrix is the stiffness with the size of 6x6. If your material is isotropic and linear elastic, both strain_x and strain_y are zero. To determine the st...
