1. Find the sum of all lines that has a syntax error (corrupted), where every bracket that causes a syntax error is given a particular value.
2. Find each line that was incomplete, complete the line and find the autocomplete score of the completed portion. For every line in the test data, we were then asked to find the median of the autocomplete scores.

1. Find the sum of all lines that has a syntax error (corrupted), where every bracket that causes a syntax error is given a particular value.
2. For each line that has a syntax error compute the string of closing characters that when appended to the line will make the line syntactically correct (i.e. "complete"). We then compute for this closing string an autocomplete score as follows: We set the score initially to 0. Then for each character of the closing string, multiply the score by 5 and then add to it a point value associated with the closing character. Finally find the median of all the autocomplete scores where the number of such scores is guaranteed to be odd.

Examples of valid pair of brackets

{([(<{}[<>[]}>{[]{[(<()> - Expected ], but found } instead.
[[<[([]))<([[{}[[()]]] - Expected ], but found ) instead.
[{[{({}]{}}([{[{{{}}([] - Expected ), but found ] instead.
[<(<(<(<{}))><([]([]() - Expected >, but found ) instead.
<{([([[(<>()){}]>(<<{{ - Expected ], but found > instead.

[({(<(())[]>[[{[]{<()<>> - Complete by adding }}]])})].

Advent of code 10 was divided into two problems

1. Find the sum of all lines that has a syntax error (corruped), where every bracket that causes a syntax error is given a particular value
2. Here we had to find each line that was incomplete, complete the line, find the autocomplete score of the completed portion. For every line in the testdata we were then asked to find the median of the autocomplete scores.
