Format Requirement

  • Algorithms in pseudo code MUST be placed in code blocks/fences, and use either the cpp or java syntax highlighter.

  • Algorithms should follow the pseudo code standard described in handout 1. 

    • Your pseudo code should be placed in a code block, for example
    Algorithm alg_name(a, b) { // A description of the algorithm // input: a - a positive decimal integer; b - an integer // ouput: the sum of a and b c = a + b // or, c <- a + b return c }
  • Do NOT change the template except the answer portion. 

  • Formulas and equations should be in math mode using Latex math symbols.
