I 9: Fill & Download for Free

I could probably make a smaller solver in C, but this is small enough for tonight.#include<stdio.h> int s[82]; int solve(unsigned i) {  unsigned ok=0x3FE;  while(s[i])i++;  if(i==81)return 1;  for(int j=0,r=i-i%9,b=((i/3)%3)*3+(i/27)*27;j<9;j++)  ok&=~((1u<<s[(i+j*9)%81])|(1u<<s[r+j])|(1u<<s[b+(j%3)+9*(j/3)]));  for(int j=1;j<=9;j++)  if(ok&(1u<<j)){  s[i]=j;  if(solve(i+1))  return 1;  }  s[i]=0;  return 0; }  int main() {  int i=0,c;  while ((c=getchar())!=EOF&&i<81) {  if (c>='0'&&c<='9') s[i++]=c-'0';  if (c=='.') s[i++]=0;  }  if (solve(0))  for (i=0;i<81;i++)  printf("%2d%c",s[i],i%9==8?'\n':' ');  else  puts("No solution"); } This weighs in at 575 characters, counting whitespace, newlines, etc. It is still fairly verbose. You could probably squeeze another 50 - 75 characters out of it easily.I trimmed it down a bit—373 characters, even with the generous “No solution” message at the end. It could be trimmed further by removing that message and removing some white space.#include<stdio.h> int p[109],i,c; int s(int k){  while(p[++k]);  int o=1,j=-1;  while(++j<9)o|=1<<p[(k+j*9)%81]|1<<p[k-k%9+j]|1<<p[k-k%27+k%9-k%3+j%3+j/3*9];  while(k-81&&(p[k]=j--)&&(o>>j&2||!s(k)));  return++j; } int main(){  for(;i-81&&(c=getchar())-EOF;i+=c>' ')p[i]='0'<c?c-'0':0;  for(s(i=-1)||(*p=0,puts("No solution"));p[++i];printf("%d%c",p[i],i%9-8?' ':'\n')); } } 

In 2003 I was laid off. My boss was a terrible manager and a worse human being, and being let go ultimately turned out to be one of the best things that happened to me professionally, but at the time it stung. After the meeting with HR to talk about COBRA, severance, etc., the HR director asked me if I wanted to speak to my boss one last time. I said that I did, and the HR director called her over. In front of the HR director, I thanked my boss for the opportunity, gave her a hug, and wished her the best.Fast forward 6 months and I’ve found a new job (at a company where I still work to this day), but when it comes time to do my I-9 employment verification, I can’t find my social security card. Now, I wasn’t born in the United States, I was a citizen through my mother’s naturalization, but I had never gotten a US passport or applied for a certificate of citizenship. That meant that I couldn’t get my social security card replaced without first getting one of those things, nor did I have any other documents proving that I was eligible to work in the United States. This was obviously a big problem, but I-9 verification doesn’t require original documents, photocopies are acceptable. And who had a copy of my social security card on file but my old employer? I ended up calling the HR director there and explaining my situation. She agreed to make me a copy of my social security card and I could come by the office and pick it up. I did, gave it to my new employer, and began my new job.The lesson that I learned (thankfully the easy way and not the hard way) was to never burn bridges. Even though it would have felt good to tell my old boss what I thought of her, I doubt that they would have done me any favors had I done that, and I would have lost out on a job offer that has led to 16 years (and counting) of very happy employment for me. And yes, I did get a passport and replace my social security card, but it took a few months.

Very Good !H = 8U = 21N = 14I = 9K = 11A = 1T = 20A = 1R = 18I = 9T = 20A = 1I think there should be no problem till now,Now for next step, just add first and last number, then second and second last number and so on till the middle number so for HUNIKA we haveHUNIKA = 8+1 , 21+11, 14+9 = 93223And TARITA becomesTARITA = 20+1, 1+20, 18+9 = 212127And now finally NIVEDITA becomes,N = 14I = 9V = 22E = 5D = 4I = 9T = 20A = 1NIVEDITA becomes,NIVEDITA = 14+1, 9+20, 22+9, 5+4 = 1529319
