Task: Given a 2D screen, location of a pixel in the screen ie(x, y) and a color K, Replace color of the given pixel and all adjacent ( excluding diagonally adjacent ) same colored pixels with the given color K. Example: Input: 1 2 2 1 1 1 1 0 1 8 Output: 8 8 8 8 Here is the Code: Program in C++: #include<iostream> #include<bits/stdc++.h> using namespace std; int main() { int t; cin>>t; while(t--) { int n,m; cin>>n>>m; int a[n][m]; for(int i=0;i<n;i++) { for(int j=0;j<m;j++) { cin>>a[i][j]; } } int x,y,k; cin>>x>>y>>k; queue<pair<int,int>> q; q.push(make_pair(x,y)); int t1 = a[x][y]; a[x][y]=k; while(q.empty()==false) { pair<int,int> t2 = q.front(); int i = t2.first, j = t2.second; if(a[i-1][j]==t1&&i-1>=0) { q.
