我幾天前就開始研究數據結構和算法,並且仍然試圖理解這些概念。我正在學習Big-O符號。我明白O(1) - 時間複雜性是什麼,並且有問題。 void Method1(int n) {
int a = 10;
int b = 20;
int x = a + n;
int y = b * n;
Console.Writeline("{0}{1}",
我正在實施一種優化算法,對於解決方案沒有或很大程度上不同的下限和上限已知或不。 要檢查,我的第一種方法是簡單地採取 if(abs(floor(log10(abs(LBD))) - floor(log10(abs(UBD)))) < 1)
{ //(<1 e.g. for 6, 13)
//Bounds are sufficiently close for the serious stu
2^n −8 = O(2^n)
It says there are some positive constants c and n0 for which
0 <= f(n) <= cg(n) for all n >= n0
我解決它: 2^n −8 <= c2^n
If c = 1, and n0 = 1
1-8 <= 1*1
-7<= 1
then for all n >= n0
