Partition of a set into K subsets with equal sum using BitMask and DP | Function to check whether K required partitions are possible or not.
Return true as the entire array is the answer.
If total number of partitions exceeds size of the array.
If the array sum is not divisible by K.
No such partitions are possible.
Required sum of each subset.
Initialize dp array with - 1.
Sum of empty subset is zero.
Iterate over all subsets / masks.
If current mask is invalid , continue.
Iterate over all array elements.
Check if the current element can be added to the current subset / mask.
Transition.
