But this approach will have O(n 3) time complexity. \$\begingroup\$ As a general rule in Python, ... and returns those as the tuple (1, 3), which get assigned to x and y respectively, which get added together to get 4. 14 lines (14 sloc) 362 Bytes Raw Blame. Pascal’s triangle is a useful recursive definition that tells us the coefficients in the expansion of the polynomial (x + a)^n. NEXT Next post: Pascal and Sierpinski Triangle. As we know the Pascal's triangle can be created as follows − In the top row, there is an array of 1. As we know that in Python, tuples are immutable, thus it cannot be changed or altered. Naive Approach: In a Pascal triangle, each entry of a row is value of binomial coefficient. Well, I'd prefer to function just quit, e.g empty return and do your sys.exit somewhere in the main block. Your function name is pascal_t, to me that looks like it returns a pascal triangle, ... Its' better to use either None for input_list default value or empty tuple. Pictorial Presentation: Sample Solution: megaapps asked on 2011-03-26. Write a Python program to check whether three given lengths (integers) of three sides form a right triangle.
