WATERCOOLER2-Review my code

[thelalitkr]

Why the following code is incorrect can someone review it?

for _ in range(int(input())):
    x,y=map(int,input().split())
    c=0
    while x<y:
        c+=1 
        x+=x 
    print(c)

your output will be wrong for when x=3 and y=5 in that case output will be 0 but according to your code output will be 1
