. Since we have found the cause, how can we improve it? The reason is that the previous computation results are not saved, causing Repeated Computation. Then, we save the previous computation results with a variable, and the modifiedCodeAs follows: VaR Fibonacci = ( Function (){ VaR Temp = {}, Value; Function F (n ){ If (N In Temp) {Value = Temp [N];} Else { If (N = 0 | n = 1 ) {Value = N ;} Else {Value = F (n-1) + f (n-2 );} Temp [N] = Value ;} Return Value ;} Return F ;})();

1 sorting using merge methods2 complete two main functions: Split and Merge3 The better way to split is to use the fast and slow hands, each time you find the middle part of the list to disassemble4 merging can be done in two ways: one is a non-recursive method and the other is a recursive method, all of which can be used.5 individuals prefer recursive methods, which are easier to understand .6 /**7 * Definition for singly-linked list.8 * struct ListNode {9 * int val;Ten * ListNode *next; One *

The principle is very simple: Flip the previous array elements, flip the array elements that follow, and finally flip the entire array element#include#defineN -using namespacestd;void Reverse (int L,int R,int* Array){ double mid= (l+r)/2.0; For (int i=l;i { Array[i]=array[r+l-i]+array[i];Array[r+l-i]=array[i]-array[r+l-i];Array[i]=array[i]-array[r+l-i]; }}int main (){ int array[n],a,b;cout"Array Length:";Cin>>a;cout"Please enter an array element:"; For (int i=0;iCin>>array[i];cout"where the loop

Last night a friend sent me a quick look at the algorithm of the article link, I think the author summed up very well, so I will only the English into Chinese, the rest remains unchanged.Disclaimer: The article content is not my original, the original link programmer all the algorithm speed check table.Data structure OperationsArray sorting algorithmDiagram operationHeap operationsProgrammer algorithm Time-space c
