Hello

I have this assignment and I do not ask you to solve it for me. What I only need is to explain it for me because seriously I spent plenty of times to just recognize what does the tasks mean and I could not.

here are the tasks:

Task 2: Calculate similarity using the following formula:

{█( 0,&ei(command)≠ ej(command)@(2×longest substring ofei(target) and ej(target) )/(lenght of ei(target)+lenght of ej(target)),&otherwise)┤

where e(command) and e(target) represent the command and target of test action e, respectively. For any i and j, s0(i, j) is in the range [0, 1]. s0(i, j)=0 if and only if the two test actions have no common substring in their targets, and s0 (i,j)=1 if and only if they have the same target. For example, s0(i, j)=10/16 =0.625 for test actions ei = “clickAndWait link=abc” and ej = “clickAndWait link=def” because the total length of targets is 16 and the common substring of targets is “link=”.

Task3: Save each similarity between ei and ej in a matrix

Thank you very much
