Question

can someone please help me solve these problem in c++ language and leave useful comments below so i can follow along and know what i am doing

/view wa New Tab CSSO IDE 15 THE DIGIT SWAP PROBLEM Write a function named swapDigitPairs() that accepts a positive integer n as an input-output parameter which is changed to a new value similar to n's but with each pair of digits swapped in order. For example: int n = 482596; int old = swapDigitPairs(n); cout << "n>" << n << ", old->" << old << endl; This returns 482597 but changes n to 845269. Notice that the 9 and 6 are swapped, as are the 2 and 5, and the 4 and 8. If the number contains an odd number of digits, leave the leftmost digit in its original place. For example: n=1234567; old = swapDigitPairs(n); cout << "n->" <ence"old->" << old << endl; This converts n into 1325476. Solve this problem without using a string. 16THE MIN-MAX STRING PROBLEM Write a function named sixStr() that accepts a string input parameter and two integer output parameters, win and max. Set in the ASC value of the smallest alphabetical character and max to the largest. Only consider alphabetical characters. The return statement should return the real ratio of sin to sax Make sure that the input string is not modified

Answer 1

#include<iostream>
using namespace std;
string swapDigitPairs(string s)
{
int len=s.length();//length of string
if(len%2==0) //if the length of string is even
{
for(int i=len-1;i>0;)
{
char a=s[i];
s[i]=s[i-1];
s[i-1]=a;
i-=2;
}
}
//if length of string is odd
else{
for(int i=len-1;i>0;)
{
char a=s[i];
s[i]=s[i-1];
s[i-1]=a;
i-=2;
}
}
return s;
}

int main()
{
string n;
cin>>n; //input the string
string old=swapDigitPairs(n);
cout<<"n - > "<<n<<" , old -> "<<old<<endl;
return 0;
}

Question 2: Minmaxstring

#include<iostream>
using namespace std;
float minmaxstring(string s)
{
int ascii[122]={0};//create an array of 122 with 0 which denote the ascii value
for(int i=0;i<s.length();i++)
{
ascii[int(s[i])]++;
}
//for finding min ascii value
float min=0;
for(int i=0;i<122;i++)
{
if(ascii[i]>=1)
{
min=i;
break; //when we find first ascii value grater than equal to 1 then we break the loop and we have our min value
}
}
float max=0;
for(int i=122;i>0;i--)
{
if(ascii[i]>=1)
{
max=i;
break; //when we find first ascii value grater than equal to 1 then we break the loop and we have our min value
}
}

return float(min/max); // return the ratio
}

int main()
{
string s;
cin>>s;
float ans=minmaxstring(s);
cout<<ans;
return 0;
}
