Define a recursive function named set_assoc; it is passed an association tuple, key, and associated value as arguments; it returns an association tuple that contains all associations with (a) a new 2-tuple added at the end for this association (if the key is nowhere in the association tuple) or (b) one of the associations changed (if the key is already in the tuple). Keep the key order the same. For example, set_assoc( ( ('a',1), ('c',3)), 'b', 2 ) returns ( ('a',1), ('c',3), ('b',2) ) set_assoc( ( ('a',1), ('c',3), ('b',2) ), 'c', 13) returns ( ('a',1), ('c',13), ('b',2) ) Hint: build a new association tuple with all associations adding the new 2-tuple at the end for a new key or creating a new 2-tuple for an existing key.

:you areto design the controller for alight that functions both as an ordinary light and also as a motion activated light and alarm. a.if the manual switch s is on, then the light l is on. b.besides the manual switch, there is a motion detector, m1, which activatesthis light.c.if motion is detected but the light is on anyway because s is on, only then a secondoutput a, an alarm, is turned on. d.the disable switch, d, disables the motion activated light and alarmbut leaves manual control operation of the light using switch s.(i)read the problem statement and clearly identify the inputs and outputs for the circuit you are designing. (ii)create the truth table for this system; include the light, alarm, switch, disable, and the motion sensor.(iii)draw a schematic of this system.
