Algorithm question 2 (a solid root of the high equation 2x ^ 4-4x ^ 3 + 6x ^ 2-8x-8 = 0)

Obtain a solid root of the high equation 2x ^ 4-4x ^ 3 + 6x ^ 2-8x-8 = 0 (accuracy requirement: 10 ^-3) Algorithm analysis is as follows: There are many real-root algorithms for High-Level equations. Here we introduce a kind of bipartite method. If the higher-order equation f (x) is set to 0, a real root algorithm is obtained using the bipartite method as follows

Sorting algorithm 0-1, 0-1-2 sort

Before encountering a very interesting topic, is about the problem of sorting algorithm:Known: An array: array element: 0 or 1 or 2Solve: Sort the array by 0-1-2?1Template classT>2 voidSwap (t t1, tT2)3 {4T tmp =T1;5T1 =T2;6t2 =tmp;7 }8 9 //sorting a array which the elements is 0

Enter an expression without parentheses, the number is less than 0-9, the output evaluates, and all the intermediate results are turned into shaping. Example: Input: 3+8x2/9-2 output: 2

The API converts the slave DNS name (or IP address) into a rack ID. Which module to use is specified by the configu
