Afghanistan has surrounded by attackers. A truck enters the city. The driver claims the load is food and medicine from Pakistanis. Yasir is one of the soldier in Afghanistan. He doubts about the truck, maybe it's from the siege. He knows that a tag is valid if the sum of every two consecutive digits of it is even and its letter is not a vowel. If the tag is invalid then Yasir need to arrest the driver of the truck with invalid tab. If it is valid the truck is allowed inside the country.Can you help yasir in determine if he need to arrest or allow the truck?

 #include <stdio.h>
int main()
{int n=0,c=0;
char tag[9];
scanf("%s",tag);
while(n<8){
    if(tag[n+1]=='-')
    n+=2;
    else if((tag[n]+tag[n+1])%2==0)
    c++;
    n++;}
if(c>=4)printf("Allowed");
else printf("Arrest");
return 0;
}

Elavenil has a chessboard with N rows and M columns. In one step, he can choose two cells of the chessboard which share a common edge (that has not been cut yet) and cut this edge. Formally, the chessboard is split into two or more pieces if it is possible to partition its cells into two non-empty subsets S1 and S2 (S1∩S2=∅, |S1|+|S2|=NM) such that there is no pair of cells c1,c2 (c1∈S1,c2∈S2) which share a common edge that has not been cut.Elavenil does not want the board to split into two or more pieces. Compute the maximum number of steps he can perform while satisfying this condition.
