Algorithms - Matrix Chain Ordering

Question

How to understand the nesting of for loops in these algorithms like which for loop comes under the other ?

Answer 1

-5 line l=2 to n.  / /chain length

So,for l=2 the 6th line for loop will run from i=1 to n-l+1 and for each i and j value of this for loop the 9th line  for loop will run from

K=i to j-1

9th line for loop is nested under 6th line for loop and 6th line for loop is nested under 5th line for loop

5--for(l=2 to n)

6--{for(I=1 to n-l+1)

     //

9{for(k=i to j-1)

     //

}

}
