Ark-U challenge

Take the zero branch

Use JCR to skip the wrong value and leave 9 in R2.

R1 starts at zero. Add a register-relative conditional jump to success so R2 finishes with 9.

Learning goals

  • Compare a register with zero
  • Use a labelled JCR target
  • Preserve the successful path

Tests

  • Program reaches HLT
  • R2 contains 9
  • Solution uses JCR
  • 1 hidden grading test
