Write a python function treasure_hunt that takes as arguments positive integers mm, nn and pp and returns the number of valid configurations of the m×nm×n grid world that follows the following rules. the "world" has mm columns and nn rows in it. there is one knight, one treasure chest and p≥0p≥0 dragon(s) in the grid-world. dragons cannot share a square with anything else. the knight can share a square with anything. dragons are indistinguishable from one another. the inputs mm and nn will satisfy 1≤m, n≤501≤m, n≤50, and pp will be a nonnegative integer less than or equal to mn−1mn−1. you may assume the code will never be run where there are no valid configurations at 1: think of the task of constructing a valid world configuration by placing the treasure, knight and dragon(s) into the grid as a sequence of tasks. how many ways are there to perform each task? where should you be using the sum rule versus the product rule? hint 2: you can import the math package in python to use the factorial function.

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?
