The second question was something like this: You get two arrays representing dice rolls And you need to find the minimum changes in the arrays so their sums will be the same. For example Arr1={5,4,6} Arr2={1,2,3,2} The answer is two because you can change 6 to 1 and 4 to 2 and you get the same sum in both of the arrays.

The first was something like: You get a string of 'a' and 'b', and you need to find how many ways you can split it into three groups, so there will be same amount of 'a' in every group. For example: 'ababa' there are 4 ways to split the string: ab ab a ; a bab a; ab a ba; a ba ba. Or for 'bbbbb' there are 6 ways to split the string.
