We will call three-digit number happy if one of its figures is equal to the sum of two others. Find the happy three-digit number 5th one after another.

260
It is obvious that the minimum three-digit numbers begin on 1 we will look as it is possible to present the sum of two figures 1=0+1 number 101 110 2=1+1=0+2 112 121 211 202 220 3=1+2=0+3 123,132,213,231,312,321 So 101,110,112,121,123,123 fifth
