Task: Given an array of integers, If a, b, c are integers in an array and satisfies the Pythagorean formulae : a^2 + b^2 = c^2 then print Yes else print No. Example: Input: 1 5 3 2 4 1 5 Output: Yes // 3,4, and 5 are Pythagorean Triplets. Here is the Code: Program in C++: #include<iostream> #include<bits/stdc++.h> using namespace std; string pythagoreanTriplet(int *a,int n) { set<int> s; for(int i=0;i<n;i++) { a[i]=a[i]*a[i]; s.insert(a[i]); } sort(a,a+n); // 4 9 16 25 36 for(int i=n-1;i>=2;i--) { int j=0; while(j<i) { if(s.find(a[i]-a[j])!=s.end()) return "Yes"; auto k = s.find(a[i]-a[j]); if(*k+a[j]>a[i]) break; j++; } } return "No"; } int main() { int t; cin>>t; while(t--) { int n; cin>>n; int a[n]; for(int i=0;i<n;i++) { cin>>a[i]
