Mahesh is very good at his analytical skills so his teacher Ramanujan wants to test his skills so he gives him a condition let's consider a rectangular R table containing N rows and M columns. Rows are numbered 1 to N from top to bottom. Columns are calculated from 1 to M from left to right. Each element of R is a non-negative number. R is pronounced steadily if the total number of elements in the ith line is not less and then the total number of elements in the i-line (1) th for each i lapho is 2 Kanye N and the total element in the Nth line is less than or equal to M. Your job is to find the number of fixed tables of different sizes N x M modulo 1 000 000 000 000 Using the Java Programming language. Input: 1 11 Output: 2
