i want to compare 1st and 2nd column and replace the element of 3rd column of B
for example,
in A when 1st and 2nd column is
[1 2] in 3rd column its corresponding value is 5
so i want to replace B's 3rd column whenever in 1st and 2nd column are 1 2
same way when [1 3] it's value will be updated in B in same format.
please help me...
