238. Product of Array Except Self | Math | Prefix Product | 4 Approaches

[@Hmmm0135]

Great Explanation

[@jeehub041]

Bhai ye O(1) extra space me bhi ban jayga just need to take the count lf zeros if zeros are more than 1 no matter what all values will be zero of zeros are 1 for sure that vak can be calculated and if no zeros in the array it's fine as well

[@paraswaghela8077]

Count the Zeroes , if more than 1 zeroes are there then entire ans array will be Zero , but if only 1 zero is there then will compute product of entire array by skipping that one zero and during computing ans array we will put zero in all ans[i] and when we encounter zero we will put product in that case ! Maybe this will work!

question tells us that don't use division operator

Thank you 😊

NICE, BROTHER. KEEP POSTING SUCH DAILY CHALLENGES! THANKS.

We can do it by using division operation also. But according to this constraint it is of no value.
class Solution {
public:
vector productExceptSelf(vector& nums) {
vector vt;
int p=1,z=1,flag=0,c=0,co=0;
for(int i=0;i

how come multiplying 30 , 10^5 times makes 30*10^5 ?? it should be 30^(10^5)
