15. Reverse Triangle Character Pattern¶ Example Pattern 15 \(N = 5\) \[\Large \begin{align} &ABCDE\\ &ABCD\\ &ABC\\ &AB\\ &A\\ \end{align} \] C++ printTriangle.cpp 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19#include <bits/stdc++.h> using namespace std; void printTriangle(int n) { for(int i=n; i>0; i--) { char ch = 'A'; for(int j=0; j<i; j++) { cout << ch++; } cout << endl; } } int main(void) { int n; cin >> n; printTriangle(n); return 0; } Input: 5 Output: ABCDE ABCD ABC AB A
