comparing the values of repeated keys in multiple columns
Hi Guyz
The 1st column of the input file has repeated keys like x,y and z. The ist task is if the 1st column has unique key (say x) and then need to consider 4th column, if it is + symbol then subtract 2nd column value with 3rd column value (we will get 2(10-8)) or if it is - symbol subtract 3rd column value with 2nd(we ll get 4 (14-10)) after that output the line with low value(2) i.e. x 10 8 + and the same follows to y and z.....etc. Thnx input Code:
x 10 8 + x 10 14 - y 10 8 + y 10 11 - z 10 8 + Code:
x 10 8 + y 10 11 - z 10 8 + |
