c算法iiv
#include <stdio.h>
int main(void)
{
unsigned long long A,B,C;
int cnt=0;
scanf("%ld%ld",&A,&B);
C=A^B;//异或运算,不同位置一
do{
cnt+=(int)(C&1); //末位为1计数
C>>=C;//右移一位
}while(C); //全零结束
printf("number of diff bit:%d\n",cnt );
}
2. 二叉树C语言算法,急!!!!

的<数据结构里>都有完整的代码,解释的也很清楚
#include<iostream>
#include<stdlib.h>

///////插入节点/////////////////////

3. 【C语言算法】求最优解
#include<stdio.h>
voidmain()
{
doubleV;
printf_s("请输入V: ");
scanf_s("%lf",&V);
intm,n,p;
intM,N,P;
doubledelta=10000.0;
for(m=0;m<=16;m++)
{
for(n=0;n<=256;n++)
{
for(p=1;p<=4096;p++)
{
doubled=m*n/(double)p-V;
if(d<0)
d=-d;
if(d<delta)
{
delta=d;
M=m;
N=n;
P=p;
}
}
}
}
printf_s("最优解:M=%d,N=%d,P=%d ",M,N,P);
}
4. 来个c语言算法大神帮帮忙!
#include<stdio.h>
#include<string.h>
void makeLDR(char DLR[],char LDR[],char LRD[],int n1)
{ int n2;
char *p=strchr(LDR,DLR[0]);
n2=p-LDR; //左子树节点数
LRD[n1-1]=DLR[0]; //赋后序根节点
if(n2>0)makeLDR(DLR+1,LDR,LRD,n2); //递归建立左子树的后序
if(n1-n2>1)makeLDR(DLR+1+n2,LDR+n2+1,LRD+n2,n1-n2-1); //递归建立右子树的后序
}
int main()
{ int i,n;
char DLR[50],LDR[50],LRD[50],c;
for(i=0,c=' '; c!=' ';) //读入左子树序列
scanf("%c%c",&DLR[i++],&c);
for(i=0,c=' '; c!=' ';) //读入右子树序列
scanf("%c%c",&LDR[i++],&c);
DLR[n=i]=LDR[i]=LRD[i]='
