Fibonacci sequence (recursion) The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is:

Python write an expression that executes the loop body as long as the user enters a non-negative number. note: if the submitted code has an infinite loop, the system will stop running the code after a few seconds and report "program end never reached." the system doesn't print the test case that caused the reported message. sample outputs with inputs: 9 5 2 -1

When a rectangular region is defined using an appropriate style, which value matches the specified edge of the clipping region to the edge of the parent element?

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
