Trace the following flowchart for the input values 3, 12, -2, 5, 15, 1, 1, 1 and complete the trace table. Also, write pre-post-conditions for this flowchart. start sum1(0 sum2-0 i+1 i+i+1 num F i≤4 sum1 +sum1 + num i+1 F i≤4 i+i+1 sum1=sum2 num T "no" "yes" sum2sum2+ num end
is the output correct.
The code was created from the flowchart in the image below
Code:
function problem2() {
// this line will grab a string from the input box.
var inputString = document.getElementById("a").value;
// process the input string similar to flowchart2 function
const values = inputString.split(',').map(Number);
let result = values[0];
let isNegative = false;
for (let i = 1; i < values.length; i++) {
if (isNegative) {
result -= values[i];
} else {
result += values[i];
}
// Check if the current number is negative and update isNegative accordingly
if (values[i] < 0) {
isNegative = !isNegative;
}
}
// Flip the sign of result only if isNegative is true at the end
if (isNegative) {
result = -result;
}
// write the result to the HTML page
document.getElementById("output").innerHTML = result;
}
