Mathematica provides a useless non-Expires header function rasterize, which can output computation results in the image format. For example, the following sentence can print the expanded "reflection" of (x + 1) ^ N ":
Today, I suddenly thought that we can use this function to easily analyze the nature of Chinese characters on images. The function binarize can convert an image into a single monochrome Channel, while imagedata can convert the image int

We know that looking for a maximum number in a data set with a capacity of N, no matter what comparison algorithm is used, it should be at least n-1 times, even if it is sorted by a competition, it will be n-1 times, otherwise, you cannot guarantee the maximum number. So what is the minimum number of comparisons between the maximum number and the minimum number in a data set with a capacity of N?The Optimal

O (n) algorithm is not said, this topic mainly examines O (logn) algorithm.An ordered array is easy to think of using a binary search solution, which is to make some adjustments on a two-point basis. The array can only be flipped once, knowing that the original ordered increment array is divided into two parts, both of which are ordered and incremented (this problem requires only the increment of an ordered array).If the inverted array is divided into two parts with the X nodes a[0..x] and A[X+1

Suppose an ordered array in ascending order is rotated from an unknown position.(e.g. 0 1 2 4 5 6 7 May become 4 5 6 7 0 1 2).Find the smallest of these elements.You can assume that there are no duplicate elements in the array.See: https://leetcode.com/problems/find-minimum-in-rotated-sorted-array/description/Class Solution {public: int findmin (vector 153
