Program to check if a given number is a strong number or not

Program to check if a given number is a strong number or not is discussed here. A strong number is a number in which the sum of the factorial of the digits is equal to the number itself.

#include<bits/stdc++.h>
using namespace std;
int fact(int num)
{
int res=1;
while(num>0)
{
res*=(num--);
}
return res;
}
bool isStrong(int num)
{
int p=num;
int res=0;
while(p>0)
{
res+=fact(p%10);
p/=10;
}
if(res==num)
return 1;
return 0;
}



int main()
{
int num=123;
cout<<isStrong(num);
}

ans+=x*x*x;
num/=10;
}
if(p==ans)
return 1;
return 0;
}
int main()
{
cout<<isArm(371);

for(int i=3;i*i<=p;i+=2)
{
if(num%i==0)
return 0;
}
return 1;

Water Jug Problem in Artificial intelligence Simple Approch

Water Jug Problem:

Problem: You are given two jugs, a 4-gallon one and a 3-gallon one.Neither has any measuring mark on it.There is a pump that can be used to fill the jugs with water.How can you get exactly 2 gallons of water into the 4-gallon jug.

Solution:

The state space for this problem can be described as the set of ordered pairs of integers (x,y)

Where,

X represents the quantity of  water in the 4-gallon jug  X= 0,1,2,3,4

Y represents the quantity of water in 3-gallon jug Y=0,1,2,3

Start State: (0,0)

Goal State: (2,0)

Generate production rules for the water jug problem

Production Rules:

Rule	State	Process
1	(X,Y | X<4)	(4,Y) {Fill 4-gallon jug}
2	(X,Y |Y<3)	(X,3) {Fill 3-gallon jug}
3	(X,Y |X>0)	(0,Y) {Empty 4-gallon jug}
4	(X,Y | Y>0)	(X,0) {Empty 3-gallon jug}
5	(X,Y | X+Y>=4 ^ Y>0)	(4,Y-(4-X)) {Pour water from 3-gallon jug into 4-gallon jug until 4-gallon jug is full}
6	(X,Y | X+Y>=3 ^X>0)	(X-(3-Y),3) {Pour water from 4-gallon jug into 3-gallon jug until 3-gallon jug is full}
7	(X,Y | X+Y<=4 ^Y>0)	(X+Y,0) {Pour all water from 3-gallon jug into 4-gallon jug}
8	(X,Y | X+Y <=3^ X>0)	(0,X+Y) {Pour all water from 4-gallon jug into 3-gallon jug}
9	(0,2)	(2,0) {Pour 2 gallon water from 3 gallon jug into 4 gallon jug}

Initialization:

Start State: (0,0)

Apply Rule 2:

(X,Y | Y<3)    ->

(X,3) {Fill 3-gallon jug}

Now the state is (X,3)

Iteration 1:

Current State: (X,3)

Apply Rule 7:

(X,Y | X+Y<=4 ^Y>0)

(X+Y,0) {Pour all water from 3-gallon jug into 4-gallon jug}

Now the state is (3,0)

Iteration 2:

Current State : (3,0)

Apply Rule 2:

(X,Y | Y<3)    ->

(3,3) {Fill 3-gallon jug}

Now the state is (3,3)

Iteration 3:

Current State:(3,3)

Apply Rule 5:

(X,Y | X+Y>=4 ^ Y>0)

(4,Y-(4-X)) {Pour water from 3-gallon jug into 4-gallon jug until 4-gallon jug is full}

Now the state is (4,2)

Iteration 4:

Current State : (4,2)

Apply Rule 3:

(X,Y | X>0)

(0,Y) {Empty 4-gallon jug}

Now state is (0,2)

Iteration 5:

Current State : (0,2)

Apply Rule 9:

(0,2)

(2,0) {Pour 2 gallon water from 3 gallon jug into 4 gallon jug}

Now the state is (2,0)

Goal Achieved.
