initially  let result sequence to be 10*  10* 10*   0* means zero or more zeroes.

every time choose two number and if we merge them produce a smaller number then we merge them.

the procedure stops until we can't merge to get a smaller number

is it correct?? seems to be..

we should modify this algo:   every time choose right most two number that we merge them can

get a smaller number then we merge them,....

we must merge numbers from right to left.... seems to be more correct

AC  with long double
