### Bachgold problem is very easy to formulate

#include <stdio.h>

int main()

{ int pos,i;

scanf("%d",&pos);

printf("%d\n",pos/2);

if(pos%2==0)

{ for(i=0;i<pos/2-1;i++)

printf("2 ");

printf("2\n");

}

else if(pos%2==1)

{ for(i=0;i<pos/2-1;i++)

printf("2 ");

printf("3\n");

}

return 0;

### Yasir has an array aops consisting of N positive integers. He would like to perform following operation on array.

#include <stdio.h>

void rudy(){}

int main()

{int n,q,aops;

int i,min,max,b;

scanf("%d %d",&n,&q);

for(i=0;i<n;i++)

scanf("%d",&aops[i]);

min=max=aops;

for(i=0;i<n;i++)

{

if(min>aops[i])

min=aops[i];

if(max<aops[i])

max=aops[i];

}

while(q–)

{

scanf("%d",&b); // number that has to be checked

(b>=min&&b<=max)?printf("Yes\n"):printf("No\n");

}

return 0;

### Venkatesa Raja is an National award wining craft artist who is famous for his “Bhakthakrisha”,

### Snowbell is a little cat. But despite the fact he is still a kitten he already knows about the pretty things that coins are.

#include <stdio.h> // what we have to check is the remainder we get by calling people one by one

void rudy(){}

int main()

{int t,n,k,c,i; // here k are the total people from whom the cat calls

scanf("%d",&t);

while(t–)

{c=0;

scanf("%d %d",&n,&k);

for(i=1;i<=k;i++) // i starts from 1 as dog has to call atleast one person

{if(n%i>c) // check if remaining coins are more than previous

c=n%i;

}

printf("%d\n",c);

}

return 0;

### Yarwanth need to find a string which has exactly K positions in it such that the character at that position comes alphabetically later than the character immediately after it

#include <stdio.h>

#include <string.h>

int main()

{char K;

char t[]="This is SHIT";

int n,v,i;

char c = 'a';

scanf("%d",&n); while(n>0){

scanf("%d",&v); for (i = v; i >=0; i–){ printf("%c", (c+i));}

strcat(K,t); printf("\n");

n–;

}

return 0;
