Write a program that replaces words in a sentence. the input begins with an integer indicating the number of word replacement pairs (original and replacement) that follow. the next line of input begins with an integer indicating the number of words in the sentence that follows. any word on the original list is replaced. assume that the list will always contain less than 20 word replacement pairs. ex: if the input is:

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.

explanation:

the difference is right there dont you see it
