Branch around the wrong value and leave 9 in t1.

The supplied value is zero. Add a conditional branch to the success label so the destination register finishes with 9.

Learning goals

  • Branch to a label
  • Preserve the successful path

Tests

  • Program exits cleanly
  • t1 contains 9
  • Solution uses BEQ
  • 1 hidden grading test
