Python program to segregate even and odd elements of array code

Copy the below python program and execute it with the help of python compiler.

def segregateEvenOdd(arr):
    # Initialize left and right indexes
    left,right = 0,len(arr)-1
 
    while left < right:
 
        # Increment left index while we see 0 at left
        while (arr[left]%2==0 and left < right):
            left += 1
 
        # Decrement right index while we see 1 at right
        while (arr[right]%2 == 1 and left < right):
            right -= 1
 
        if (left < right):
              # Swap arr[left] and arr[right]*/
              arr[left],arr[right] = arr[right],arr[left]
              left += 1
              right = right-1

arr = [12, 34, 45, 9, 8, 90, 3]
segregateEvenOdd(arr)
print ("Array after segregation "),
for i in range(0,len(arr)):
    print arr[i],

def segregateEvenOdd(arr):

# Initialize left and right indexes

left,right = 0,len(arr)-1

while left < right:

# Increment left index while we see 0 at left

while (arr[left]%2==0 and left < right):

left += 1

# Decrement right index while we see 1 at right

while (arr[right]%2 == 1 and left < right):

right -= 1

if (left < right):

# Swap arr[left] and arr[right]*/

arr[left],arr[right] = arr[right],arr[left]

left += 1

right = right-1

arr = [12, 34, 45, 9, 8, 90, 3]

segregateEvenOdd(arr)

print ("Array after segregation "),

for i in range(0,len(arr)):

print arr[i],

Program Output

Array after segregation 12 34 90 8 9 45 3
