Any function that is passed into exec_2() will be executed twice without parameters. Your task is to write a function exec_4(f) that takes in a function f as a parameter and executes the function f 4 times using the function exec_2. The function f in this case will draw a cute koala bear, and, in conjunction with, exec_4(), you will draw 4 koalas on the same tree! Suppress the newline in the print statement for the koala, this can be done using print's end argument.

What is one reason why indoor air pollution has become an increasing problem.

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
