Question

This is R language

• Initialize two variables: i, to 1 as before, and found, to FALSE.
• Write a while loop that:
• keeps running as long as found is FALSE.
• Checks if logs[[i]]$success is FALSE and logs[[i]]$details$location equals "waste". You'll need to use the && sign here. This causes the evaluation of the condition to halt as soon as the result of the condition is known; if logs[[i]]$success is TRUE, it's certain that the condition will be FALSE, so the next comparison is not evaluated anymore.
• prints out "found" and sets found to TRUE if the above condition holds.
• prints out "still looking" and increment i if the above condition does not hold.

# Initialize i and found
i <- 1
found <- FALSE

# Code the while loop
while (___) {
if (___ && ___) {
  
} else {
  
}
}

Solution

# Initialize i and found
i <- 1
found <- FALSE

# Code the while loop
while (!found) {
if (!logs[[i]]$success && logs[[i]]$details$location == "waste") {
print("found")
found <- TRUE
} else {
print("still looking")
i <- i + 1
}
}
