easy to understand for beginners solution in Clear category for End Zeros by nandhakumar19984
def end_zeros(num: int) -> int:
a=str(num) #convert int into string
count=0 #setting a counter to count how many zeros from end
for i in reversed(range(len(a))): #reversed() use to iterate from reverse order
if a[i]=='0': #checks its a zero or not
count+=1 #if it is zero,increase the counter
else:
break #any other number comes other than zero from reverse order,break the solution
return count #return the counter that we counted
if __name__ == '__main__':
print("Example:")
print(end_zeros(0))
# These "asserts" are used for self-checking and not for an auto-testing
assert end_zeros(0) == 1
assert end_zeros(1) == 0
assert end_zeros(10) == 1
assert end_zeros(101) == 0
assert end_zeros(245) == 0
assert end_zeros(100100) == 2
