Ex $4)$ Trace the following flowchart for when input values are $12,2,-3,6,-11,-3,1,-1$ and complete the trace table. Also, write pre$-$post$-$conditions for this flowchart.

Ex $5)$ This exercise uses sub$-$algorithms. Trace the algorithm when input value is $4$ and complete the trace tables. Also note that there are two variables named num. One is in the main algorithm and another is the sub$-$algorithm. Write pre$-$post$-$conditions for each of these algorithms $($the

main one and the sub$-$algorithm$).$

I need javascript code for this not flowchart trace table
