/* http://codeforces.com/contest/426/problem/C 最多交换k个数的顺序,求a[i]的最大连续和 爆解 思路:Lets backtrack interval that should contain maximal sum. To improve it we can swap not more then K minimal elements in fixed interval to not more K maximal elements not conta…

C语言中要实现交换两个数的值,可以有很多种方法,具体如下所述. 不使用中间变量: // 异或, a^=b^=a^=b; a ^= b; b ^= a; a ^= b; // 加减 a = a + b; b = a - b; a = a - b; // 乘除 a = a * b; b = a / b; b = a/ b; 使用中间变量: // 需临时空间 temp = a; a = b; b = temp; 正如你所想的那样,上面所示代码只是描述了交换两个数的值的思想,在你实际使用时,还有诸多地方…

在编程过程中,交换两个数是我用常用的 ,这里做下简单的搬运 bool Widget::swap(int a, int b) { int temp =a; a= b; b = temp; } 这种方式其实是没有改变的ab两个参数的值的,只有在函数里面,ab的值是改变的,但是在函数外面,ab的值还是没有改变的 bool Widget::swap_point(int *a, int *b) { int temp = *a; *a = *b; *b = temp; } 这样才是改变了ab的值 另外 ,交…

问题1:实现pow(int x, int y) ,即x的y次方 x的y次方就是有y个x连续乘机,代码如下: #include <stdio.h> #include <stdlib.h> int my_pow(int x,int y){ ) ; ; for(;i<y;i++){ ret=ret*x; printf(,ret); } return ret; } int main(){ ,); printf("====%d\n",tmp); ; } 结果 [ro…
