I KNOW THE CODE IS A BIT COMPLEX.MAY BE THERE IS A BETTER WAY TO SOLVE THE SAME QUESTION BUT I AM NOT GETTING THAT CASE ON WHICH IT FAILS SO PLS HELP.

# include<stdio.h>

int g(int c);

int main()

{int a,x,k,te,b,z,m,j,e,c,d,i,t;

int f;

scanf("%d",&a);

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

{ scanf("%d",&t);

k=t;

d=g(t);

for(b=0;b<d;b++)

 { f[b]=t%10;

t=t/10;

}


te=0;

m=0;

x=0;

if(k>1)

{

while(--k)

{ while(d--)

{

x=f[m]*k+te;

f[m]=x%10;

te=x/10;

m++;

}

while(te)

{

f[m]=te%10;

te=te/10;

m++;

}

d=m;

e=m-1;

m=0;

te=0;

}

for(j=e;j>=0;j--)


{printf("%d",f[j]);}

printf("\n");

}if(k==1)

printf("1");


}

return 0;}

int g(int c)

{int a=0;

while(c)

{a=a+1;

c=c/10;

}

return a;}
