Can anyone help me in identifying the error in this program for bubble sort?
def bsort(a):
for i in range (0, len(a)-1):
for j in range(i):
if a[j]> a[j+1]:
temp = a[j]
a[j] = a[j+1]
a[j+1] = temp
num = [1,2,6,5,7,2,5,9]
bsort(num)
print(num)
It sorts the list only once.
更改外循环中的范围:
for i in range (0, len(a)):
Minor issues in for loop.
def bsort(a):
for i in range (0, len(a)-1):
for j in range(len(a)-2): ## updated here
if a[j]> a[j+1]:
temp = a[j]
a[j] = a[j+1]
a[j+1] = temp
num = [1,2,6,5,7,2,5,9]
bsort(num)
print(num)
Output is [1, 2, 2, 5, 5, 6, 7, 9]
