pair off true and false

[brian005]

hi

i need to pair off an array of boolean, the following is the rules

1.pair off OFF-ON, not ON-OFF
2.pair from the beginning of array to the end
3.input is an array of boolean, output is the index of elements which haved been paired off

attached is an example

how can i do that?

thanks in advance

Why are 6 and 9 paired off?

Sorry, forget to mention that

this pair seems like the C grammar

{                                              // 1

          {                                   // 2

           .......

          }                                  // 3

}                                            // 4

so 1 must pair 4, and 2 pair 3

A few more bits of info would be helpful.

Is your boolean array always the same size? Maybe, array size is odd, even or both.

How many F->T indent nest levels can there be?
