Answer 1

Answer:

include<stdio.h>

#include<string.h>

void calculate(char *a, int i, int n);

void swap (char *x, char *y);

int m=0;

int main()

{

char str[10] = "LT";

int len=0,i=0;

len = strlen(str);

calculate(str, 0, len-1);

printf("%d\n",m);

>

void swap (char *x, char *y) {

char temp:

temp = *x;

*x=*y;

*y = temp:

void calculate(char *a, int i, int n) {

int ;=0;

if(i== n) {

mtt;

else {

for (i = i; j<=n; j++){

swap((a+i), (a+j));

calculate(a,i+1, n);

swap((a+i), (a+j));
