Write an if-else statement that if numDifference is greater than stringDifference, execute totalDifference = -35. Else, execute totalDifference numDifference. 1 let totalDifference 0; 2 let numDifference = -18; // Program will be tested with -18, -19 and -20 3 let stringDifference = "-19"; 4 5 /* Your solution goes here */ 6
