Problem specification: kynet became self-aware and Judgement Day happened, inevitably. The machines are narching against the human race wielding futuristic weapons. But the humans will not go gentle nto the good night and the fight for survival is fierce. While many humans meet the cold hard teel at the front line with plasma cannons, you work for the resistance as a specialist in cyber varfare. Skynet uses radio communication to transmit binary numbers and thus coordinate its roops on the ground. However, before transmitting the number, it is heavily encrypted. The inary number is first converted to an alphabetic string (for example, 110 is converted to neonezero) and then as an added layer of security, the letters in the string are rearranged (for xample, oneonezero is rearranged to nznooeeoer). Being a legendary hacker, your task is to atercept these messages and attempt to decipher them. Given an encrypted alphabetic string, ou want to calculate the number of possible binary values it can represent. For example, the tring nznooeeoer can represent a total of 3 binary values (011, 101 and 110). nput specification: he input is a string composed of the English lowercase letters: 'z', 'e', 'r', 'o' and 'n'. You can safely assume that it is possibi o rearrange the letters in such a way that they form a sequence of words, each word being either "zero" which correspond o the digit 0 or "one" which corresponds to the digit 1. The number of letters in the string will not exceed 90. Dutput specification: he output of your program is a single integer that represents the number of binary values that the input string can represen lote: You must not print anything extraneous (such as “Please enter string" or “the result is"). Sample input: Sample output: ozer 1 oneonezero

Problem specification: Skynet became self-aware and Judgement Day happened, inevitably. The machines are marching against the human race wielding futuristic weapons. But the humans will not go gentle into the good night and the fight for survival is fierce. While many humans meet the cold hard steel at the front line with plasma cannons, you work for the resistance as a specialist in cyber warfare. Skynet uses radio communication to transmit binary numbers and thus coordinate its troops on the ground. However, before transmitting the number, it is heavily encrypted. The binary number is first converted to an alphabetic string (for example, 110 is converted to oneonezero) and then as an added layer of security, the letters in the string are rearranged (for example, oneonezero is rearranged to nznooeeoer).
