Transcribed Image Text:#include <stdio.h> void Permute(char* source) { : //·enter code here } int main() { return 0; }
Expert Solution
Step 1: Code
#include<stdio.h>
#include<string.h>



void swap(char *x, char *y)
{
chartemp;
temp = *x;
*x = *y;
*y = temp;
}

 

void permute(char *a, int l, int r)
{
int i;
if (l == r) {
printf("%s ", a);
 
}
else
{
for (i = l; i <= r; i++)
{
swap((a+l), (a+i));
permute(a, l+1, r);
swap((a+l), (a+i));
}
}
}

 

int main()
{
charstr[] = "ABC";
intn = strlen(str);
permute(str, 0, n-1);
return0;
}
