Round-1 Implement a data structure similar to Hashmap that maps integer to integer, but with additional methods: get(key), set(key, x),:- usual as a normal hashmap, incr_value(s), incr_key(s):- they respectively increment integer value of all "values" of the keys, and all "keys" of the dictionary by the value "s" eg:- if dat_str={1:10, 4:12} and I call dat_str.incr_value(7), I get dat_str as {1:17, 4:19}. Further if I now call dat_str.incr_key(7), I get dat_str as {8:17, 11:19).
