25. Write an object-oriented program to read a set of lines from stdin and store them in an array A;

again read a string S from the stdin and check whether the given string S in the array A. If it is, remove string S from the array A and print the updated array on the stdout. For example,

A = concatenate S = cat

The updated a is conenate.

26. Write an object-oriented program to read a set of lines from stdin and store them in an array A; again read strings S1 and S2 from the stdin and check whether the given string S1 is in the array

A. If it does, replace the string S1 with string S2 and print the updated array. For example,

A = concatenate S1 = cat

S2 = 123

The updated A is con123enate
