Dadas dos variables n1 y n2. La tarea es intercambiar los valores de ambas variables sin usar la tercera variable.
Ejemplos:
X : 10 Y : 20 After swapping X and Y, we get : X : 20 Y : 10
Python
# Python code to swap two numbers
# without using another variable
x = 5
y = 7
print ("Before swapping: ")
print("Value of x : ", x, " and y : ", y)
# code to swap 'x' and 'y'
x, y = y, x
print ("After swapping: ")
print("Value of x : ", x, " and y : ", y)
Python
# Python code to swap two numbers
# using Bitwise XOR method
x = 5 # x = 0101
y = 10 # y = 1010
print ("Before swapping: ")
print("Value of x : ", x, " and y : ", y)
# Swap code
x ^= y # x = 1111, y = 1010
y ^= x # y = 0101, x = 1111
x ^= y # x = 1010, y = 0101
print ("After swapping: ")
print("Value of x : ", x, " and y : ", y)
Python
# Python code to swap two numbers
# using + and - operators
x = 5.4
y = 10.3
print ("Before swapping: ")
print("Value of x : ", x, " and y : ", y)
# Swap code
x = x + y # x = 15.7, y = 10.3
y = x - y # x = 15.7, y = 5.4
x = x - y # x = 10.3, y = 5.4
print ("After swapping: ")
print("Value of x : ", x, " and y : ", y)
Python
# Python code to swap two numbers
# using / and * operators
x = 5.4
y = 10.3
print ("Before swapping: ")
print("Value of x : ", x, " and y : ", y)
# Swap code
x = x * y # x = 55.62, y = 10.3
y = x / y # x = 55.62, y = 5.4
x = x / y # x = 10.3, y = 5.4
print ("After swapping: ")
print("Value of x : ", x, " and y : ", y)
Python3
# python program to swap two numbers
# using bitwise addition for swapping
x = 5;
y = 10;
print ("Before swapping: ") ;
print("Value of x : ", x, " and y : ", y) ;
# same as x = x + y
x = (x & y) + (x|y) ;
#vsame as y = x - y
y = x + (~y) + 1 ;
# same as x = x - y
x = x + (~y) + 1 ;
print ("After swapping: ")
print("Value of x : ", x, " and y : ", y)
