Discussion on: JavaScript Code Daily Challenge #9

[Lakshya Tyagi]

It's a JavaScript Series but this time i tried a python code for it

t=int(input())
for i in range(0,t):
    n=int(input())
    k=int(input())
    if(n==2):
        print(1)
    elif(k%n==0):
        print(0)
    else:
        r=k%n
        if(r==(n-r)):
            print(n-1)
        elif(r<(n-r)):
            print(2*r)
        else:
            print(2*(n-r))
