You've got an array consisting of n integers: a, a, ..., a[n]. Moreover, there are m queries, each query can be described by three integers li, ri, ki. Query li, ri, ki means that we should add to each element a[j], where li ≤ j ≤ ri.
Record means the binomial coefficient, or the number of combinations from y elements into groups of x elements.
You need to fulfil consecutively all queries and then print the final array.
