Question 1: The user will enter a list of numbers and a separate number. The program will display the index at which the number is present in the list. If the number is absent, it'll return -1. Do NOT use built-in functions for searching.

n=list(input("enter a list of numbers(without any , or space):"))
num=input("enter the number:")
if num in n:
    b=len(n)
    for m in range(0,b):
        if num==n[m]:
            print("index of the number in the given list is ",m)
else:
    print("this number is not in the list")
