Code to solve 4 4’s problem : write each of the numbers 1 to 100 using exactly four 4’s for each number
now for each function,make a function that performs on the first element, and keeps a record in the 2nd
Now we start making lists of numebrs, starting with numbers reachable from one 4: 4, .4 = 4⁄10, and .4 repeating = 4⁄9, and we apply all unary ops to them
