The index of a Fibonacci number
Statement
The Fibonacci sequence is defined as follows: $$ \phi_0 = 0, \ \phi_1 = 1, \ \phi_n = \phi_{n1} + \phi_{n2} . $$ Given an integer \( a \), determine its index among the Fibonacci numbers, that is, print the number \( n \) such that \( \phi_n = a \). If \( a \) is not a Fibonacci number, print 1.In all the problems input the data using input()
and print the result using print()
