In binary representation there are some states that believed to be never occurred due to some particular functionality of a given circuit. If zero output is assigned to such states then it is called minimal risk solution as  we are resetting the formidable states which could be occurred accidentally. Another approach is to assigned a don't care to them so it results in lesser logic and hence is called minimal cost solution.

 #include<stdio.h>
int main(){
    int num,r,sum=0,temp;

    printf("Enter a number: ");
    scanf("%d",&num);

    temp=num;
    while(num){
         r=num%10;
         num=num/10;
         sum=sum*10+r;
    }
    if(temp==sum)
         printf("%d is a palindrome",temp);
    else
         printf("%d is not a palindrome",temp);

    return 0;
}

Sample output:
Enter a number: 131
131 is a palindrome

In the early 20th century, the Balkans were called a "powder keg" because the political situation in the region was very unstable. For a long time, the Ottoman Turks occupied the balkans, and with the rise of nationalism, some balkan states declared independence.

Mitochondria which is present in both plant and animal cells supplies energy to the cells and hence called as the powerhouse of the cell.

The mammalian heartis called myogenic (myo = muscle, genie = originating from). It means the heart beat or the activities of the heart are auto regulated which originates from a muscle called nodal tissue.In the human heart,heartbeat originates and contraction is initiated by a special modified heart muscle known as sinoatrial node. It is located in the right atrium; while the QRS waves are the depolarisation of the ventricles, which initiates the ventricular contraction.The T-wave represents the repolarisation,that is, the return of the ventricles from excited tonormal state.Hepatic portal system is the unique vascular connection that exists between the digestive tract and liver. This vein carries blood from intestine to the liver.
