WebApproach 1 (Brute Force Recursion) We know that each number in this triangle is the sum of the two numbers directly above it. i.e. Num (row,col)= Num (row-1,col) + Num (row-1,col-1). So we can repeatedly call the function Num (rowIndex,j) for each column index of that row, and return the formed list. As we can see we have formulated recursive ...
