1. Define a struct for stocks that has fields for symbol, price and number of shares 2. Create the stocks listed in the comments 3. Create a cash struct with name myCash and value of 200 4. Define a function valueOf that takes one investment as its argument 5. Define a function compareValue that takes two investments as arguments and returns true if the first argument is greater than the second, and false otherwise 6. Define a function indMaxValue that takes a list of investments and returns the investment with the greatest value. 7. Define a function findMaxValue2 that uses local bindings 8. Use filter to create a list of iust investments with more than ten shares 9. Use fold to calculate the total value of all the items in iovestmentlist 1.
