In GO Lang

Now edit the file hw1.go so it is in package main

a function CalcPressure that takes 3 parameters: v, n, t, which represent volume, amount (also called molarity) and temperature of an ideal gas and returns the pressure the gas is under

the parameters and return type are all of type float64
the pressure is calculated by the ideal gas law: p = nRt/v, where R is the Ideal Gas Constant
volume is in cubic meters, amount is in moles, temperature is in degrees Kelvin and pressure is in pascals (newtons per square meter). This makes R = 8.3144598

The encrypted text e and the return type are []byte, but the code c is a map of byte to byte

If the code map does not contain the byte, just use the byte. For example, the standard substitution ciphers that replace letters with other letters leave spaces and punctuation alone.
Ex: suppose c[‘e’] = ‘u’, c[‘h’] = ‘f’, c[‘l’] = ‘n’, c[‘o’] = ‘y’. Then Decode([]byte(“hello”), c) should return the slice of bytes [‘f’, ‘u’, ‘n’, ‘n’, ‘y’]

A function OddParity that takes a slice of ints and returns two values. The first return value is true if the list has an odd number of 1’s, false if it has an even number of 1’s. The second return value is true if all values are 0’s or 1’s, false if there are any other values (like a 52).

This function gives you a reason to use a loop
Ex: OddParity([]int{0,1,1,1}) should return true, true

Write main() to demonstrate that your functions work as desired. You should have two calls for each function to prevent yourself from hard-coding the wrong things as well as to capture different cases. The OddParity cases should cover both true and false for both return values.
