Example
Input
Number of rows: 5
Output
5 5 5 5 5
4 4 4 4
3 3 3
2 2
1
Explanation
Here, a pyramid is printed such that if the number of rows is n=5, then the ith row has 6i printed (6i) times with spaces in front and between the numbers, where 1=<i<=n.
Approach
Firstly we will take the input for the number of rows. And to print the inverted full pyramid number pattern, we will use two for loops. And, we will calculate the number of times both the loops should run and what they should it print.
 If the number of rows is n, then the outer loop will run for n times, and there will be two inner loops.
 One inner loop will ensure the spaces before the starting number of every row.
 The number of spaces will be i1 at the starting of ith row.
 And the second inner loop will be printing the number ni+1, (ni+1) times.
Program in C++
Now we will solve this problem on how to print the inverted full pyramid number pattern by taking the number of rows as inputs from the user in C++.
Code
#include<bits/stdc++.h>
using namespace std;
int main() {
int n;
cout<<"Number of rows: ";
cin>>n;
int space=0;
for(int i=n;i>=1;i){
for(int j=0;j<space;j++){
cout<<" ";
}
space++;
for(int j=0;j<i;j++){
cout<<i<<" ";
}
cout<<"\n";
}
return 0;
}

FAQs

What is the benefit of pattern puzzles?
Solving a pattern puzzle is the best way to learn the use of loop statements and practice some logical problems.

What will be the time complexity of the inverted full pyramid number pattern program?
O(n^{2}) will be the time complexity because the inner loops will run ((n)+(n1)+...+1) times which is n*(n+1)/2. So, the time complexity is O(n^{2}).

What will be the space complexity of the inverted full pyramid number pattern program?
O(1) will be the space complexity because no extra space was used.
