Question

In MIPS code and should be able to run on MARS 4.5, create a program that finds the number of times the letters K, N, I, G, H, T, and S are used in a sentence that the user inputs. YOU MUST SHOW A SCREENSHOT OF THE OUTPUT AND MUST RUN ON MARS 4.5

Sample Input by user:

Hello, the cat jumped over the kitten and walked down the road to grab some food. The dog ran across the feild and fetched the ball. The Gardner mowed the lawn.

Sample Ouput should be in the following format:

K: # of times said

N:# of times said

I:# of times said

G: # of times

H: # of times

T: # of times

S: # of times
