Check the explanation
Step-by-step explanation:
C+++ CODE:
#include<bits/stdc++.h>
using namespace std;
//implementing function calculateWays
int calculateWays(int wordlen , int maxvowels)
{
//if max vowels = 0 calculating ways
if(maxvowels==0)
{
int ways = 1;
//loop for calculating ways
for(int i=0 ; i<wordlen ; i++)
{
ways = ways*21;
}
return ways;
}
else
{
if(wordlen==1)//if word length is 1
{
int c = 1, v = 1;
int ways = c*21 + v*5; //calculating ways
return ways;
}
else // if max vowels and world length both are greater then 1
{
int ways = 0;
//loop to calculating
for(int i=0 ; i<wordlen ; i++)
{
int c = 1, v = 1;
for(int j=0 ; j<wordlen-maxvowels ; j++)
{
c = c*21;
}
for(int k=0 ; k<maxvowels ; k++)
{
v = v*5;
}
ways = ways + (v*c); // calculating ways with vowels
}
int ways1 = 1;
for(int i=0 ; i<wordlen ; i++)
{
ways1 = ways1*21; //calculating ways without vowels
}
return ways + ways1 ; //return total ways
}
}
}
int main()
{
int wordlen , maxvowels;// declaring variables
cin>>wordlen>>maxvowels; // reading inputs from user
int ways = calculateWays(wordlen , maxvowels); //passing values to function calculateWays
cout<<ways; //printing ways
return 0;
}
