Answer:
public static boolean beginsWithZ(String word){
if(string == null || string.length() == 0)
return 0;
if(word.charAt(0) == 'Z' || word.charAt(0) == 'z')
return 1;
else
return 0;
}
Explanation:
This method is a boolean method, meaning it returns true if the string begins with Z or z and false otherwise. So:
The Java command charAt() let's you find the character at each position of the string, so i use it.
public static boolean beginsWithZ(String word){
if(string == null || string.length() == 0)
return 0;
if(word.charAt(0) == 'Z' || word.charAt(0) == 'z')
return 1;
else
return 0;
}

Answer:
def newton(n):
#Define the variables.
t = 0.000001
esti = 1.0
#Calculate the square root
#using newton method.
while True:
esti = (esti + n / esti) / 2
dif = abs(n - esti ** 2)
if dif <= t:
break
#Return the result.
return esti
#Define the main function.
def main():
#Continue until user press enters.
while True:
try:
#Prompt the user for input.
n = int(input("Enter a number (Press Enter to stop):"))
#display the results.
print("newton = %0.15f" % newton(n))
except:
return
#Call the main function.
main()
