TCS NQT Online Course - bit.ly/TCS-NQT-and-Ninja-Course

[@harsh_here]

We could have simply divid N by 2, and if N is odd the Nth element will become the (N/2 +1)th element of the first series. Whereas if N is even, it is the N/2th element of the second series. Which we can easily find out as we know the r for each series. We don't need a loop at all. It's a simple if-else problem

[@laxus7764]

These questions are nothing compared to what is asked in Qualcomm preliminary exam 😭😭

[@shrajalkumar964]

the way you explained is really good.... and so is the logic ... apart from that i just wanna ask..... in place of "if(a==1) condition" , can we go with "if(a>1) {a=a*2}" and intiate a and b equals to 1

Hi how to prepare amcat and cocubes

[@akashsingh2655]

We need to find an output on PC during exam time or we just need to write a code somewhere???

[@PrepInsta]

They will give you an online compiler in the system which will automatically run your code against pre defined inputs. Three inputs will be show and 3 will be hidden

[@abhisheks802]

this can be an easy approach..without taking loops and all.. x = int(input("Enter position:")) y = x/2 if (y).is_integer(): y = y-1; z = 1*pow(3,y); z = int(z); else: a = int(y); z = 1*pow(2,a); z = int(z) print(z)

[@TamilselvanR599]

Why dont u make it constant time complexity? If N is odd: { return 2^Floor(N/2); } If N is even: { Return 3^((N/2)-1); }

[@namansaxena8624]

I was thinking the same thing bro.

[@RAHULROY-oc4ro]

there's no need of floor function. by default int/int produce result as int, as example 7/2 is 3 by default.

Sohail, usually TCS asks for 60 % throughout, so if you have less than 60% in any of your academics so it could be a bummer. But don't lose hope, there will be other opportunities as well.
