@Vikas It was my observation. @abhishek Sum of digits will be 8 because all the digits tell you the number of times they appear
Lets just say the number is Number --> a b c d e f g h @Digits > 0 1 2 3 4 5 6 7 a+b+c+d+e+f+g+h = 8 One more observation : a*0 + b*1 + c*2 + d*3 + e*4 + f*5 + g*6 + h*7 = 8 for example if at 3digit position we have '2' in the number then 3 will be present twice in the number so at the positions, '3' is present in the number ,those digits will be present 3 times hence 3*2=6 digits because of 3digit position. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
