- First, read in an input value for variable valCount. Then, read valCount integers from input and output each on the same line wrapped in curly braces. End with a newline. Ex: If the input is 3 75 -25 -55, the output is: {75}{-25}{-55} #include <iostream>using namespace std; int main() { int valCount; cin >> valCount; int inputNum; for (int i = 0; i < valCount; i++) { cin >> inputNum; cout << "{" << inputNum << "}" << endl; } return 0;} Input 3 75 -25 -55 Your output {75} {-25} {-55} Expected output {75}{-25}{-55} check2: Compare outputkeyboard_arrow_up Input 1 70 Your output {70} clear3: Compare outputkeyboard_arrow_up Output is nearly correct, but whitespace differs.
