Write a program, named sortlist, that reads three to four integers from the command line arguments and returns the sorted list o

yawa3891 [41]

Answer:

In C++:

void sortlist(char nums[],int charlent){

int Myarr[charlent];

const char s[4] = " ";

char* tok;

tok = strtok(nums, s);

int i = 0;

while (tok != 0) {

int y = atoi(tok);

Myarr[i] = y;

tok = strtok(0, s);

i++;

}

int a;

for (int i = 0; i < charlent; ++i) {

for (int j = i + 1; j < charlent; ++j) {

if (Myarr[i] > Myarr[j]) {

a = Myarr[i];

Myarr[i] = Myarr[j];

Myarr[j] = a;

} } }

for(int j = 0;j<charlent;j++){ printf(" %d",Myarr[j]); }

}

Explanation:

This line defines the sortlist function. It receives chararray and its length as arguments

void sortlist(char nums[],int charlent){

This declares an array

int Myarr[len];

This declares a constant char s and also initializes it to space

const char s[4] = " ";

This declares a token as a char pointer

char* tok;

This line gets the first token from the char

tok = strtok(nums, s);

This initializes variable i to 0

int i = 0;

The following while loop passes converts each token to integer and then passes the tokens to the array

while (tok != 0) {

int y = atoi(tok); -> Convert token to integer

Myarr[i] = y; -> Pass token to array

tok = strtok(0, s); -> Read token

i++;

}

Next, is to sort the list.

int a;

This iterates through the list

for (int i = 0; i < charlent; ++i) {

This iterates through every other elements of the list

for (int j = i + 1; j < charlent; ++j) {

This condition checks if the current element is greater than next element

if (Myarr[i] > Myarr[j]) {

If true, swap both elements

a = Myarr[i];

Myarr[i] = Myarr[j];

Myarr[j] = a;

} } }

The following iteration prints the sorted array

for(int j = 0;j<charlent;j++){ printf(" %d",Myarr[j]); }

}

What are the advantages and disadvantages of solving a problem that can be broken down into repetitive tasks with recursion as o

lesantik [10]

Answer:

Answered below

Explanation:

Recursion refers to the process of a function calling itself within its own definition. It calls itself repeatedly until a base condition is met and the loop breaks.

The advantages of recursion over loops include;

A) Recursion reduces time complexity.

B) Recursion is better at tree traversal and graphs.

C) Recursion reduces the time needed to write and debug code and also adds clarity to code.

Disadvantages of recursion include;

A) Recursion uses more memory because each function call remains in stack until the base case is met.

B) Recursion can be slow.

C) Recursion
