5- Amaliy mashg`ulot
Mavzu: “Ajrat va hukmronlik qil” prinsipi bo‘yicha ishlaydigan algoritmlarni loyihalash. Elementlar jamlanmasini biror belgi bo‘yicha tartiblashtirish algoritmi. Bog‘langan graflarda marshrutlar, ularni narxi(masofasi) bo‘yicha baholash. Xasis algoritmlar. Eng qisqa marshrutni aniqlash algoritmi. Uni variantlar soni bo‘yicha hajmini baholash. Kruskal algoritmi. Prima algoritmi. Xoffman algoritmi.
Ishdan maqsad: “Ajrat va hukmronlik qil” prinsipi bo‘yicha ishlaydigan algoritmlarni loyihalash. Elementlar jamlanmasini biror belgi bo‘yicha tartiblashtirish algoritmi.
Amaliy qism:

#include

int binarqidiruv(char a[],int b, int o, char x){
if(o>=b)
{int mid=b+(o-b)/2;
if(a[mid]==x) return mid;
if(a[mid]>x) return binarqidiruv(a, b, mid-1, x);
return binarqidiruv(a, mid+1, o, x); } return -1;}
using namespace std;
int main()
{ int n;
cout<<"Massiv elementlari sonini kiriting: "; cin>>n;
char a[n];
cout<<"Massiv elementlarini kiriting: ";
for(int i=0; i{ cin>>a[i];} for (int i=n-1; i>0; i--)
{for(int j=0; ja[j+1]) {swap (a[j],a[j+1]); }}}
cout<<"Saralangan massiv: ";
for(int i=0; icout<cout<<"Qidirilayotgan elementni kiriting: "; cin>>x;
int natija=binarqidiruv(a, 0, n-1, x); cout<

Xulosa
Bu mavzuda biz “Ajrat va hukmronlik qil” prinsipi bo‘yicha ishlaydigan algoritmlarni loyihalash. Elementlar jamlanmasini biror belgi bo‘yicha tartiblashtirish algoritmi usulidan foydalanishni o`rgandik.
