Exercises

Dynamic programming

Deep Sum

Write a recursive function whose input is a list containing lists up to any depth containing positive integers. The function must return the sum of all numbers inside the list.

Example:

[1, 2, 3, [4, 5], [[[6], 7]]] -> 28

Palindrome

Write a recursive function which checks whether a given string is a palindrome or not. Then try to write a non recursive function for that and compare the time complexity.

Example:

aba -> True 
abb -> False

Factorial

Write a recursive function to compute the factorial of a given natural number. Then try to write a non recursive function for that and compare their time complexity.

Sum Digit

Write a recursive function to compute the sum of the digits of a given positive integers.

Example:

234-->9

Sum Series

Write a recursive function to compute sum of the series n+(n-2)+... for a given input n.

Parenthesis

Given a string, replace the enclosed parts of the string with a $ character. A formula is enclosed if it is surrounded by parenthesis. For example:

(xc)aa(c(b)) -> $$$$aa$$$$$$
