Python program to place and the most significant digit of number
Write a complete Python program to do the following :
(i) read an integer X.
(ii) determine the number of digits n in X.
(iii) form an integer Y that has the number of digits n at ten's place and the most significant digit of X at one's place.
(iv) Output Y.
(For example, if X is equal to 2134, then Y should be 42 as there are 4 digits and the most significant number is 2).
Solution
x = int(input("Enter an integer: "))
temp = x
count = 0
digit = -1
while temp != 0 :
digit = temp % 10
count += 1
temp = temp // 10
y = count * 10 + digit
print("Y =", y)
Output
Enter an integer: 2134
Y = 42
