Quick Start

solution.typ

// Import the package
// For local development, use lib.typ directly
#import "lib.typ": problem, test

// Display the problem
#problem(1)

// Write your solution
#let solution(nums, target) = {
  let d = (:)
  for (i, num) in nums.enumerate() {
    if str(target - num) in d {
      return (d.at(str(target - num)), i)
    }
    d.insert(str(num), i)
  }
}

// Test with built-in cases!
#test(1, solution)
