Write a function: def solution (s) that, given a string s of letters "l" and "r", denoting the types of shoes in line (left or right), returns the maximum number of intervals such that each interval contains an equal number of left and right shoes. for example, given s "rlrrllrlrrll", the function should return 4, because s can be split into intervals: "rl, "rrll", "rl" and "rrll". note that the intervals do not have to be of the same size.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
