Parsing line and selecting values corresponding to a key
- by gagneet
there is a set of data which is arranged in a specific manner (as a tree), as is given below. basically a key=value pair, with some additional values at the end, which informs how many children does the branch have and some junk value.
11=1 123 2
11=1>1=45 234 1
11=1>1=45>9=16 345 1
11=1>1=45>9=16>2=34 222 1
11=1>1=45>9=16>2=34>7=0 2234 1
11=1>1=45>9=16>2=34>7=0>8=0 22345 1
11=1>1=45>9=16>2=34>7=0>8=0>0=138 22234 1
11=1>1=45>9=16>2=34>7=0>8=0>0=138>5=0 5566 1
11=1>1=45>9=16>2=34>7=0>8=0>0=138>5=0>4=0 664 1
11=1>1=45>9=16>2=34>7=0>8=0>0=138>5=0>4=0>6=10 443 1
11=1>1=45>9=16>2=34>7=0>8=0>0=138>5=0>4=0>6=10>3=11 445 0
11=1>1=47 4453 1
11=1>1=47>9=16 887 1
11=1>1=47>9=16>2=34 67 1
11=1>1=47>9=16>2=340>7=0 98 1
11=1>1=47>9=16>2=34>7=0>8=0 654 1
11=1>1=47>9=16>2=34>7=0>8=0>0=138 5789 1
11=1>1=47>9=16>2=34>7=0>8=0>0=138>5=0 9870 1
11=1>1=47>9=16>2=34>7=0>8=0>0=138>5=0>4=0 3216 1
11=1>1=47>9=16>2=34>7=0>8=0>0=138>5=0>4=0>6=10>3=11 66678 0
my problem is to get the appropriate branch from the above data, which satisfies exactly the values, which i give as the input.
suppose, my input value to search in the above data stack are:
5=0
4=0
6=10
3=11
11=1
1=45
0=138
9=16
2=34
7=0
8=0
for the above given list of key-values, the function should return 11=11=459=162=347=08=00=1385=04=06=103=11 as the match.
likewise, for another input file, in which another set of keys is given:
5=0
4=0
6=10
3=11
11=1
1=45
9=16
2=34
7=0
8=0
the function should return 11=11=459=162=347=08=0 1 as the match. not the last line; as that would also match all the values given in my input key, but, i want only the exact match.
Also, I want to find out how many nodes were selected in the given array. (separated by ).
What will be the best way to implement this kind of scenario?
