array

Refering to the solution present at MIT handout

I have tried to figure out the solution myself but have got stuck and I believe I need help to understand the following points.

In the function header used in the solution

MEDIAN -SEARCH (A[1 . . l], B[1 . . m], max(1,n/2 - m), min(l, n/2))

I do not understand the last two arguments why not simply 1, l why the max and min respectively.

Thanking You.

I'm new to coding , learning it since last year actually.

One last example was the following (see paste… >>> More
