The first remainder characters of the string will occur quotient + 1 times. Similarly, marks1, marks3, marks5, and so on denote the marks of girls. deletions = 0 My solution is pretty much the same, except that I didn't want to accumulate as much memory (storing the entire grid can be pretty expensive in terms of memory) and used a bitset instead of hashtable for checking used values, since most of the time it's going to be full anyways, so hashtable only adds performance and memory overhead :) The alternating elements marks0, marks2, marks4, and so on denote the marks of boys. 0 Comment.
