My issue

it is giving runtime error again and again ?

My code

t=int(input())
for i in range(t):
    N, K=map(int,input().split())
    remainder = N % K
    if K != 0:
        remainder = N % K
        if remainder > K//2:
            print(K - remainder)
        else:
            print(remainder)
    else:
        print(0)

Why have you declared the variable “remainder” twice in the code?
