$"123"$ is a string commonly found in weak passwords. Replace the occurrences of $"123"$ in keyWord with $"651".$

Ex: If the input is $12376$jn$>$$NXh@z$9,$ then the output is:

Valid password: $65176$jn$>$$NXh@z$9$

Note:

string.find$($item$)$ returns the index of the first occurrence of item in string. If no occurrence is found, then the function returns string::npos.

string.replace$($indx$,$ num, subStr$)$ replaces characters at indices indx to indx$+$num$-1$ with a copy of subStr.
