What is running time of ALG1 in -notation?

ALG1(A, n) l=0 for i = 0 to n-1 do for j =i to n-1 do if ALG2(A, i, j) and j-i +1>1 then l=j-i+1 ALG2(A, i, j) if i =j then return true end if for k= i to j1 do if A[k] # A[k + 1] then return false end if end for return true end if end for end for return 1
