Entertaining task

Recently I found here such an interesting task and decided to share it with the habrasociety. Actually the task itself:

In the written expression (((((1? 2)? 3)? 4)? 5)? 6 instead of each sign "?" insert the sign of one of the four arithmetic operations: +, -, *, / so that the result of the calculation is 35 (when dividing, the fractional part in the quotient is discarded). It’s enough to find one solution
