// Phase 164: Test Pattern3 (If-Else PHI) without break
// Pattern3 is: if-else PHI with NO break, NO continue
// Example: Accumulate result with conditional assignment
// Simulates: loop(i < n) { if condition { result = f(result) } else { result = g(result) } i++ }

static box Main {
  main(args) {
    // Accumulate sum with conditional increment
    // Pattern: if-else PHI where variable gets different values in both branches
    local i = 0
    local sum = 0
    local n = 5

    loop(i < n) {
      // If-else PHI: sum gets different values in each branch
      if i == 2 {
        sum = sum + 10  // Branch 1: add 10
      } else {
        sum = sum + 1   // Branch 2: add 1
      }
      i = i + 1
    }

    // Output result
