Wrathchild:the number is called Kaprekar's constant named after Kaprekar mathematician from india..495 is the 3 digit version of it
Got it - thanks  aa chal ke tujhe main leke chalu ik aise gagan ke tale jahan gam bhi na ho, aansoo bhi na ho,bas pyaar hi pyaar pale |

Anand_n:
Transcendental:
its not like a puzzle,because if u understand it, u can do it easily..its about a 4 digit number which is special in a way.. take any 4 digit number in which numbers are non repeating..say 1234 the maximum number that can be formed by rearranging it 4321 the least number that can be formed from rearranging it 1234 take the difference 4321-1234 = 3087..now re arrange this as above 8730-378 = 8352 re arrange it again 8532-2358 = 6174. do it again..7641-1467=6174..this iteration ends with 6174. take any other example and try it out..u will always end up with 6174 finally. this works for only non repeating 4 digit numbers.. |

Nisarga: sorry. d=2 and N=9 in this case
You are right - it needs another limiting factor ...yours looks more theoretically correct - validate cheyyaledu
New_ccid: Do you think it's Anad's formula, anyways, I really appreciate Anand�s memory power and patience to work on that old paper work.
LOL - it would not have errors like Nisarga found if it was not something I derived
Jkm:mee patience ki hats off. mee maths, logical thinking too much andi. 5 stars icha. naaku 2 mins think chestunte thala noppi vastondi.

What is the least 4 digit number that can be arrived at by taking any non repeating 4 digit number(1111 4444 etc) playing/re arranging it in such a way that the difference of the maximum value(after re arranging) and least value (after re arranging) is always the least 4 digit number? Note: You will have to repeat the process of rearranging the number you obtain after taking difference every time until you arrive at the least number. |

Transcendental:How did you derive This formula?..
more of serendipity i guess . I thought this way: total number of digits available = 10 ( i.e 9,8,7,6,5,4,3,2,1,0 ) D number of digits can be picked in ways P(10,D) = 10! / (10-D)! the picked are in descending are in ways = 1/D! So, the total number of ways : P(10,D) * 1/D! Not sure this works correctly for all the number of digits ( of course D<=10 )  |

I think the right formula would be C(10,D); i.e. (10!)/((10-D)! * D!) where D is the number of digits. however D=1 is excluded . |

Anand_n:(N)*M(1) + (N-1)*M(2) + (N-1)*M(3) ......(1)*M(N) Say for 5 digit number we solved yesterday it was - N=6 6*1 + 5*4 + 4*10 + 3*25 + 2*35 + 1*56 = 252 For an 8 digit number, N= 3 3*1 + 2*4 + 10 = 21
what about for a 2 digit number! d=9;N=2. Does the formula work?? |

Jkm:there are n number of formulas. but once you have the formula in your hand, it will be easy to write code. you need pen and paper/black board to derive the formula.
Well, I knew that, I could make your code, even simpler way too. You know what, as long as you have the formula, it’s not at all a big deal to write the code, even in assembly language too. I totally agree with you. It’s pretty easy to write the code in several diff ways. What I mean to say is, there is no best solution for any given problem, it just depends on the time and situation, do you got me? |

Jkm, There is no proven mathematical formula in this world buddy, till some other mind, provides the evidence that it's wrong, we gotta live with that one. However, as I said before, there are N numbers of solutions for any given problem. We just gotta pick one out of N that dish up the current goal in a superior style. Take it easy. |

Here is a simple c program to do the job. That too, after having some Glenfiddich, I am furnishing for u ;) It’s works for 0 to 10 digits numbers. No Offence. world become small cause of sharing zeor's and one's from one node to other, no need to have that old math stuff, its gonna be a paper less world. Here you go. int StrictlyDesOrderDigitNums(int iNumDig) { unsigned long lNum = 0; int iCount = 0; int dig1 = 0; int dig2 = 0; bool bFlag = true; unsigned long lMaxLim = 0; int iLastSrs = iNumDig - 1; int iSrsCount = 0; if ( iNumDig > 10 ) { printf("Get a life buddy,this works only for 10 base system\n"); } else if ( iNumDig == 10 ) { printf("9876543210\n"); return 1; } for (int i=0; i < iNumDig; i++ ) { lMaxLim = (lMaxLim * 10) + 9; lNum = (lNum * 10) + iNumDig - (i + 1); } while ( lNum < lMaxLim ) { long lTest = lNum; bFlag = true; while ( lTest > 10 ) { dig1 = lTest%10; lTest = lTest/10; dig2 = lTest%10; if ( dig1 >= dig2 ) { bFlag = false; break; } } if ( bFlag ) { if ( iLastSrs != lTest ) { printf("\nSeries count: %d\n\n", iSrsCount); iLastSrs = lTest; iSrsCount = 0; } printf("%d ", lNum); iCount++; iSrsCount++; } lNum++; } printf("\nSeries count: %d\n\n", iSrsCount); return iCount; } int main(char* argv[], int argc) { printf("\nTotal count: %d\n", StrictlyDesOrderDigitNums(5)); return 0; } |

Aha - figured out the formula for any number of digits.Ninna only 6 digit solve chesanu ... Here's the formula for people who are like me and can't let a puzzle go Some definitions first : S(x) = 1+2+3....+ x i.e. Sum of x natural numbers e.g. S(1) = 1, S(2) = 3, S(3) = 6....S(6) = 21 M(y) = Progressive sums of y S(x), M(Y) = S(1) +S(2) + S(3) + s(4) .....S(Y) M(1) = 1, M(2) = 4, M(3) = 10..... M(6) = 56 The key factor in the puzzle is the number of options for the units place.The higher the number of digits ,lower the number of unit place options. To find the number of unit place options(N) - subtract the number of digits(d) from 11. N = 11- d so for 5 digits , d = 5, N=6 For 8 digits, d=8, N=3 Now the formula for number of d digit numbers with descending digits - (N)*M(1) + (N-1)*M(2) + (N-1)*M(3) ......(1)*M(N) Say for 5 digit number we solved yesterday it was - N=6 6*1 + 5*4 + 4*10 + 3*25 + 2*35 + 1*56 = 252 For an 8 digit number, N= 3 3*1 + 2*4 + 10 = 21 Enjoy  aa chal ke tujhe main leke chalu ik aise gagan ke tale jahan gam bhi na ho, aansoo bhi na ho,bas pyaar hi pyaar pale |

How many 5 digit numbers are there in which the digits are in "strictly" descending order; For example 98543; You see all the digits are in strictly descending order. 99876 is not a "strictly" descending order. This one takes some time to work out the solution.

Transcendental:The key to the solution is to engage both the persons to find the answer. So, you ask the first person to get the answer from second. You can derive the correct answer from that response.
if we phrase the questin in such a way tat gate keeper has to answer twice,but still u ask one question.... something like..if i say this road will lead to heaven will you say yes? then if this question si asked to a liar he will have to lie 2 times and one lie cancels the other.. |

This is a fair solution only when pointing to the road is not implicated as a question with in itself....A signal posing a question....even in this solution U ASK @ QUESTIONS!!!! |

again above scenario hold if both of them cal speak more than yes or no. If they can only answer in yes or no..then the answer is different....in that case... Pick one person and ask: "Do both of you speak the truth and is this the way to heaven" By assumptions: Liar should say : Yes both of us speak the truth and the way he points is not the way so take the other way True person should say: No and should point in the right way |
