Chapter 7.9, Problem 25CP
Program Plan Intro

List:

  • • A list is an object that has sequence of elements.
  • • The contents of the list can be changed at any point of time, so lists in Python are mutable.
  • • Lists support various additional operations like “append()”, “insert()”, “remove()”, “del()”, etc.
  • • Lists have a dynamic size.
  • • Lists store elements of same type, i.e. lists are homogenous.
  • • List elements are enclosed by square brackets.

Syntax:

The syntax to create a list is as follows:

List_name = [element1, element2,…, elementn]

Explanation:

Here,

  • • “List_name” specifies the list name.
  • • “element1, element2, and elementn” indicate the list elements.

Example program:

Consider the below example that creates a list and prints the list.

#Declare a list with numbers

list_ex = [1, 2, 3, 4]

#Print the list

print(list_ex)

Sample Output:

[1, 2, 3, 4]

Program explanation:

In the above code,

  • • “list_ex” represents a list having integers as its elements.
  • • Then, the list “list_ex” is printed using “print()” function.

Tuple:

  • • Tuple is an object that has immutable sequence of elements.
  • • The contents of the tuple cannot be altered once it is created. Therefore, tuples in Python are immutable.
  • • Tuples have a static size.
  • • The elements of tuples can be of various types, i.e. tuples are heterogeneous.
  • • Elements in the tuple are enclosed by parenthesis.

Syntax:

In python, a tuple is created using the below format.

#Create a tuple

Tuple_name = (element1, element2, …, elementn)

Explanation:

  • • “Tuple_name” specifies the tuple name.
  • • “element1, element2, and elementn” indicate the tuple elements.

Example program:

Consider the below example that creates a tuple and prints the tuple.

#Declare a tuple with numbers, strings

tuple_ex = [1, 'Joe', 'Tom', 4]

#Print the tuple

print(tuple_ex)

Sample Output:

[1, 'Joe', 'Tom', 4]

Program explanation:

In the above code,

  • • “tuple_ex” represents a tuple having integers and strings as its elements.
  • • Then, the tuple “tuple_ex” is printed using “print()” function.

The next problem concerns the following C code: /copy input string x to buf */ void foo (char *x) { char buf [8]; strcpy((char *) buf, x); } void callfoo() { } foo("ZYXWVUTSRQPONMLKJIHGFEDCBA"); Here is the corresponding machine code on a Linux/x86 machine: 0000000000400530 : 400530: 48 83 ec 18 sub $0x18,%rsp 400534: 48 89 fe mov %rdi, %rsi 400537: 48 89 e7 mov %rsp,%rdi 40053a: e8 d1 fe ff ff 40053f: 48 83 c4 18 add callq 400410 $0x18,%rsp 400543: c3 retq 0000000000400544 : 400544: 48 83 ec 08 sub $0x8,%rsp 400548: bf 00 06 40 00 mov $0x400600,%edi 40054d: e8 de ff ff ff callq 400530 400552: 48 83 c4 08 add $0x8,%rsp 400556: c3 This problem tests your understanding of the program stack. Here are some notes to help you work the problem: • strcpy(char *dst, char *src) copies the string at address src (including the terminating '\0' character) to address dst. It does not check the size of the destination buffer. You will need to know the hex values of the following characters:
A ROP (Return-Oriented Programming) attack can be used to execute arbitrary instructions by chaining together small pieces of code called "gadgets." Your goal is to create a stack layout for a ROP attack that calls a function located at '0x4018bd3'. Below is the assembly code for the function 'getbuf', which allocates 8 bytes of stack space for a 'char' array. This array is then passed to the 'gets' function. Additionally, you are provided with five useful gadgets and their addresses. Use these gadgets to construct the stack layout. Assembly for getbuf 1 getbuf: 2 sub $8, %rsp 3 mov %rsp, %rdi 4 call gets 56 add $8, %rsp ret #Allocate 8 bytes for buffer #Load buffer address into %rdi #Call gets with buffer #Restore the stack pointer #Return to caller. Stack Layout (fill in Gadgets each 8-byte section) Address Gadget Address Value (8 bytes) 0x4006a7 pop %rdi; ret 0x7fffffffdfc0 Ox4006a9 pop %rsi; ret 0x7fffffffdfb8 0x4006ab pop %rax; ret 0x7fffffffdfb0 0x7fffffffdfa8 Ox4006ad mov %rax,…
In each of the following C code snippets, there are issues that can prevent the compilerfrom applying certain optimizations. For each snippet:• Circle the line number that contains compiler optimization blocker.• Select the best modification to improve optimization.1. Which line prevents compiler optimization? Circle one: 2 3 4 5 6Suggested solution:• Remove printf or move it outside the loop.• Remove the loop.• Replace arr[i] with a constant value.1 int sum( int ∗ ar r , int n) {2 int s = 0 ;3 for ( int i = 0 ; i < n ; i++) {4 s += a r r [ i ] ;5 p r i n t f ( ”%d\n” , s ) ;6 }7 return s ;8 }2. Which line prevents compiler optimization? Circle one: 2 3 4 5 6Suggested solution:• Move or eliminate do extra work() if it’s not necessary inside the loop.• Remove the loop (but what about scaling?).• Replace arr[i] *= factor; with arr[i] = 0; (why would that help?).1 void s c a l e ( int ∗ ar r , int n , int f a c t o r ) {2 for ( int i = 0 ; i < n ; i++) {3 a r r [ i ] ∗= f a c t o r…
