Score : 300 points
Problem Statement
You are given three integers A, B and C. Find the minimum number of operations required to make A, B and C all equal by repeatedly performing the following two kinds of operations in any order:
Choose two among A, B and C, then increase both by 1.
Choose one among A, B and C, then increase it by 2.
It can be proved that we can always make A, B and C all equal by repeatedly performing these operations.
Constraints
0≤A,B,C≤50
All values in input are integers.
